Tom Selleck, an enduring figure in Hollywood. has captivated audiences for decades with his rugged charm, iconic moustache. and memorable roles in television and film. From his breakout role as Thomas Magnum in Magnum P.I. to his current portrayal of Frank Reagan in Blue Bloods. Selleck's career has spanned over 50 years. But beyond his professional achievements. fans have often been curious about Tom Selleck Health. especially as he has aged in the public eye.
Follow us on: Pinterest
Introduction
Many have been interested in Tom Selleck health. not only because of his enduring presence on screen but also because of the challenges. and lifestyle choices he has faced and made over the years. This article delves into the various aspects of Tom Selleck health. exploring his fitness regimen, diet, mental health. and the challenges he has encountered as he ages. We'll look at how he maintains his well-being. the health issues he has faced, and his approach to ageing .
Early Life and Career
Childhood and Athletic Beginnings
Tom Selleck was born on January 29, 1945, in Detroit, Michigan, and grew up in Sherman Oaks, California. From an early age, he was involved in sports, particularly basketball. which played a significant role in his physical development. His athletic pursuits continued into college. where he attended the University of Southern California (USC) on a basketball scholarship. This early involvement in sports laid a strong foundation for his physical health and disciplined lifestyle.
Transition to Acting
Selleck's transition from an athlete to an actor came with its physical demands. His first significant role in "Magnum P.I." required him to perform various stunts and maintain a fit appearance. This role, which he played from 1980 to 1988. necessitated a rigorous fitness routine to meet the show's demands. setting the stage for his long-term commitment to health and wellness.
Fitness Regimen
Workout Routine
Tom Selleck health and fitness regimen has evolved. adapting to his changing roles and age. During his "Magnum, P.I." days. Selleck's workouts were intense and focused on building and maintaining muscle mass. His routine included weightlifting, cardiovascular exercises. and specific training for the stunts he performed on the show.
Selleck adjusted his fitness routine as he aged to suit his body's needs. Today, his workouts focus on maintaining flexibility, strength, and cardiovascular health. He incorporates low-impact exercises such as swimming, walking, and light weightlifting. This balanced approach helps him stay fit without putting undue strain on his joints and muscles.
Importance of Flexibility and Mobility
In recent years, Selleck has emphasized the importance of flexibility and mobility in his fitness regimen. Understanding the natural decline in muscle mass and joint flexibility with age. he includes stretching and yoga in his routine. These practices help prevent injuries, improve posture, and maintain mobilit

Basavarajeeyam is an important text for ayurvedic physician belonging to andhra pradehs. It is a popular compendium in various parts of our country as well as in andhra pradesh. The content of the text was presented in sanskrit and telugu language (Bilingual). One of the most famous book in ayurvedic pharmaceutics and therapeutics. This book contains 25 chapters called as prakaranas. Many rasaoushadis were explained, pioneer of dhatu druti, nadi pareeksha, mutra pareeksha etc. Belongs to the period of 15-16 century. New diseases like upadamsha, phiranga rogas are explained.
Muktapishti is a traditional Ayurvedic preparation made from Shoditha Mukta (Purified Pearl), is believed to help regulate thyroid function and reduce symptoms of hyperthyroidism due to its cooling and balancing properties. Clinical evidence on its efficacy remains limited, necessitating further research to validate its therapeutic benefits.
3. JAUNDICE
Jaundice is a syndrome ,the hallmark of which
is yellowish discoloration of body tissues
produced by an excess of circulating bilirubin
(conjugated or unconjugated)
Normal serum bilirubin is ranging from 0.1-1
mg % and jaundice is detected clinically in
the sclera of the eye when the level rises above
2.5 mg%
It is most evident in tissues which have a high
elastic tissue content (skin –sclera of the eye –
blood vessels)
4. BILIRUBIN METABOLISM
Bilirubin is formed from haem (a compound of iron and
protoporphyrin) , Haem comes from breakdown of mature red cells
in the reticuloendothelial system
This unconjugated bilirubin which is water insoluble is toxic and
transported attached to plasma proteins to the liver cells
In the hepatic cells it is conjugated into water soluble bilirubin
(conjugated bilirubin)
Conjugated bilirubin is excreted into the bile canaliculi
Disturbance of the flow of bile led to stagnation and retention of
conjugated bilirubin (cholestasis)which may occur in the
intrahepatic bile ducts (intrahepatic cholestasis)or in the extrahepatic
bile ducts (extrahepatic cholestasis)
5. Mechanisms of jaundice
)1(Excess bilirubin production
)2(impaired uptake and transport of bilirubin by the hepatocytes
)3(failure of conjugation
)4(Impaired secretion of conjugated bilirubin into the bile canaliculi
)5(Impaired bile flow subsequent to secretion by the hepatocyte
Thus there are 3 categories of jaundice
Haemolytic jaundice)1(
Hepatocellular jaundice)2-4(
)Obstruvtive jaundice)5
7. The term cholestatic jaundice may be
intrahepatic (hepatic disease impairing
transport of conjugated bilirubin from the
hepatocyte to bile canaliculi and intrahepatic
ducts)
or Extrahepatic (from large bile duct
obstruction)
The later is referred to as surgical jaundice

NON-INVASIVE METHODS
1-ULTRASOUND
Ultrasonography is both sensitive and specific in
detecting gallbladder stones and dilatation of bile ducts.
Ultrasound usually misses stones in the common duct.
When ultrasound shows dilated bile ducts, THC will
nearly always be technically successful.
14. ultrasound image demonstrate the normal gallbladder The thin wall of
the gallbladder is seen as a white ring surrounding bile, which appears
as a black fluid. The wall thickness should be less than 3 mm in adults.
article41.htmlarticle41.html
15. 2-SPIRAL C.T.
Spiral C.T. with I.V. contrast enhancement
is essential in all patients with suspected
tumours
I.V. superparamagnetic ferric oxide
(endorem) which yields even greater definition
This shows liver tumours as white areas (no
kupffer cells) against a black background
(contrast in kupffer cells)
17. 3-RADIONUCLIDE SCAN (HIDA SCAN)
Technetium 99m-labeled derivatives of
iminodiacetic acid (IDA) are excreted in high
concentration in bile and produce excellent
gamma camera images.
Following intravenous injection of the
radionuclide, imaging of the bile ducts and
gallbladder normally appears within 15–30
minutes.
18. 4-Magnetic Resonance Imaging
Available since the mid-1990s, MRI provides
anatomic details of the liver, gallbladder, and
pancreas similar to those obtained from CT.
Using MRI with newer techniques and contrast
materials, accurate anatomic images can be
obtained of the bile ducts and the pancreatic duct.
It has a sensitivity and specificity of 95 and 89%,
respectively, at detecting choledocholithiasis.
19. 5-MAGNITIC RESONANCE
CHOLANGIOPANCREATOGRAPHY (MRCP)
Is completely non-invasive and does not require
injection of contrast
It is a specialized type of MRI that uses radio
waves and magnets to obtain pictures of the
bile ducts
20. INVASIVE METHODS
1-PERCUTANEOUS TRANSHEPATIC
CHOLANGIOGRAPHY
PTC is performed by passing a fine needle through
the the hepatic parenchyma and into the lumen of a
bile duct. Water-soluble contrast material is injected,
and x-ray films are taken.
The technical success is related to the degree of
dilatation of the intrahepatic bile ducts. THC is
especially valuable in demonstrating the biliary
anatomy in patients with lesions of the proximal bile
duct, or when ERCP has been unsuccessful.
21. These two radiographs demonstrate the skinny needle used to
puncture the bile duct during PTC.
22. THC should not be done in patients with
cholangitis until the infection has been
controlled with antibiotics.
Virtually all patients should be premedicated
with antibiotics regardless of whether they
have cholangitis or not
septic shock has been produced by sudden
inoculation of organisms from bile into the
systemic circulation
23. 2-ENDOSCOPIC RETROGRADE
CHOLANGIOPANCREATOGRAPHY (ERCP(
ERCP involves cannulating the sphincter of
Oddi under direct vision through a side-viewing
duodenoscope.
Usually, it is possible to opacify the pancreatic
as well as the bile ducts.
It is usually the preferred method of examining
the biliary tree in patients with presumed
choledocholithiasis or obstructing lesions in the
periampullary region.
24.
25. The endoscope transmits dynamic images of the lumen of
the gut allowing the physician to carefully examine the
lining. During the procedure air is blown into the digestive
tract to expand mucosal folds making examination
thorough
26. The ERCP is usually performed in the radiology department under
fluoroscopic guidance. The patient is sedated, and the endoscope inserted
through the mouth into the duodenum. The physician looks for the major
duodenal papilla to insert the guide catheter to perform the retrograde
study of the biliary tree
27.
28. This picture shows the catheter from the endoscope within
the papilla. This allows the physician to perform a
retrograde filling of the biliary tree.
29. This picture shows the major duodenal
papilla before the endoscope is inserted.
30. 3-Endoscopic ultrasonography (EUS(
With the considerable advances in transducer
technology and related image-processing software
,EUS has been shown to be extremely useful for
the diagnosis and staging of bile duct and
proximal pancreatic pathology
A more recent development is intraductal
ultrasonography (IDUS( where a fine transducer
probe is introduced in the bile or pancreatic duct
at ERCP
31.
32.
33. 4-Laparoscopy with laparoscopic contact US
This provides the most senitive and reliable
assessment ,staging of hepatic ,biliary and
pancreatic cancers
34. C- LIVER BIOPSY
Should not be done until a bleeding tendency
has been excluded
The procedure is hazardous in the presence
of ascites
Hydatid disease of the liver must be excluded
as accidental puncture can spread the disease
throughout the peritonial cavity or give rise to
anaphylactic shock
36. 1-GALLSTONES & DUCTAL CALCULI
Gallstones are very common worldwide ,the prevalence is
18% with a female preponderance (2-1(
The currentaly accepted classification recognizes 3 main
types of gallstones
A-cholesterol stones: essentially metabolic stones that form in
the gall bladder
B-black pigment stones : form in the gall bladder and consist
of bilirubin pigments with a varrying amount of cholesterol
C- brown pigment stones :form in the bile ducts (primary
ductal stones( ,they are amorphous soft stones that consist of
calcium bilirubinate and palmitate bound in a matrix of
organic material
37. DUCTAL CALCULI
Ductal calculi can result from migration of gallstones
through a patent cystic duct (secondary ductal calculi –
black pigment calculi( or formed de novo in the ducts
(primary ductal calculi-brown pigment stones(
Ductal calculi may form around foreign bodies within
the lumen of the common bile duct ,a common
example of this nowadays is caused by the
internalization of titanium metal clips used to secure
the medial end of the cystic duct stump during
laparoscopic cholecystectomy ,the patient present
several months after an uneventful L.C.with jaundice
and /or cholangitis
38. ERCP demonstrates stones in the common bile duct on
the left radiograph, and cystic duct on the right radiograph
39. CLINICAL TERMS TO DESCRIBE DUCTAL CALCULI
UNSUSPECTED STONES
Are those discovered accidentally when routine
intraoperative cholangiography is performed
,these stones are usually small and floating and
the C.B.D. is of normal caliber
MISSED STONES
Are stones missed after intervention (surgical or
endoscopic) that fails to achieve complete ductal
clerance
Ductal calculi that diagnosed within 2 years of the
intervention are described as missed stones
40. RECURRENT STONES
Present at least 2 years after the first intervention
These tend to be primary ductal stones (brown
pigment stones)and are almost always
associated with dilatation of the C.B.D.
41. MANAGEMENT
1-GALLSTONES AND DUCTAL CALCULI
Cholecystectomy is only indicated for symptomatic
gallstones and their copmlications (acute
cholecystitis,acute pacreatitis ,jaundice due to ductal
calculi)
There is now firm evidence from several prospecive
randomized trials that “early” cholecystectomy for
acute cholecystitis (operation within the same hospital
admission )is superior to “delayed” cholecystectomy
(2-3 month after resolution of the attack )provided the
patient is fit for surgery and anaesthesia
42. operative cholangiogram. The catheter is inserted into the cystic duct
and contrast media injected as radiographs are taken. The entire distal
biliary tree is demonstrated without stone or dilation of the ducts. This
confirms that stones are limited to the gallbladder, which was removed
43. The benefits of early cholecystectomy include
Reduced overall morbidity
Reduced hospital stay
Prevention of further attacks that may occur in
patients managed by yhe delayed
cholecystectomy policy
Unfit patients should be treated conservatively in
the first instance with the expectation that acute
cholecystitis will resolve in 80% of cases
44. If this conservative treatment fails or in cases
with empyema of the G.B. an ulrasound
laparoscopically guided cholecystostomy or
microcholecystostomy (under u/s guidance )
will tide the patient over the critical illness
45. The current treatment for patients with
concomitant ductal stones is preoperative
endoscopic stone extraction followed by
cholecystectomy preferably during the same
hospital admission
Single stage L.C. and ductal stone clerance either
by the transcystic route (stones <6mm )or by
laparoscopic supraduodenal direct C.B.D.
exploration (large stones) is prefered in some
centres instead of the two-stage approach
46. A large cholesterol stone (white arrow) is released
from a wire basket into the duodenum
47. sphincterectomy (blue arrow) was performed to
allow a stone to be removed and release
stagnated bile into the duodenum
49. T-tube cholangiogram. The tube inserted into the common bile duct. As you
can see the tube is long extending to the outside of the body.
50. 22--PANCREATIC DISEASEPANCREATIC DISEASE
Periampullary cancers are usually resectable and
are treated by pancreatoduodenectomy if the
patient is fit for major surgery
By contrast most proximal pancreatic
adenocarcimomas are not resectable and are
managed palliatively (biliary bypass) with
stenting (by interventional endoscopy or
interventional radiology)
51. In patients with jaundice thought to be due to chronic
pancreatitis the options are between a formal
pancreatoduodenectomy or subtotal resection of the head
leaving a rim of pancreas in the duodenal curve and
releasing the transpancreatic duct (Beger’s procedure)
Amodification of Beger’s procedure involves transection
of the bile duct just above the pancreas with reimplantation
into the duodenum , Both operations preserve the duodenum
If there is doubt concerning the diagnosis the appropriate
procedure is a formal pancreatoduodenectomy
52. 3-BILIARY TRACT MALIGNANCIES
A-CARCINOMA OF THE GALLBLADDER
is the most common malignancy of the
biliary tract and accounts for 3-4 % of all
gastrointestinal malignancies
It is a disease of old age and carries a poor
prognosis
Gall stones are present in 75-90% of cases
53. B-BILE DUCT CANCERS (cholangiocarcinomas)
1-intrahepatic:from major hepatic ducts
2-proximal:from right and left hepatic ducts ,hilar
confluence and proximal CHD
3-middle :from distal CHD ,cystic duct and its
confluence with the CHD
4-distal: included with periampullary tumours
Radiologically they give rise to a stricture with
proximal dilatation
54.
55. TREATMENT OF BILIARY MALIGNANCY
cacinoma of the gall bladder is a miserable
disease that is always incurable when
diagnosed clinically
Palliation of the jaundice and itching due to
involvement of the C.H.D. is achieved by
endoscopic or radiological stenting
In the rare instance when the disease is
resectable and the patient is fit resection is
indicated
56. If the tumour invades the hepatic parenchyma
a right hepatectomy with resection of the
C.B.D.and nodal clearance is performed
In selected cases if the lesion is confined to the
G.B. the liver resection is limited to the gall
bladder bed
57. Middle and distal bile duct tumours are
resected with removal of the pancreas and
duodenum
Proximal tumours (hilar) may be resected if the
patient’s condition is good . The resection
extendes beyond the bifurcation and must
always include the caudate lobe
Non-resectable or inoperable bile duct tumours
can be either stented or bypassed surgically
58. Expandable metalic wall stents give better
palliation than plastic stents
There is some debate as to whether surgical
palliation should include a gastroenterostomy
in addition to biliary bypass
59. 4-HEPATIC
MALIGNANCY
hepatic malignancy can be primary (H.C.C.)
or secondary from a primary in another site
The presence of jaundice in association
with liver tumours indicate extensive
involvement of the liver parenchyma with the
patient being incurable and unlikely to
benefit from any form of treatment
60. HEPATOCELLULAR CARCINOMA
may arise on a morphologically normal liver or
complicate established cirrhosis
The aetiology is varied but the vast majority is the
result of HBV or HCV
Some cases are associated with oral
cotraceptives and androgenic steroids
Ingestion of food contaminated with aflatoxins
produced by fungus Aspergillus flavus has been
incriminated in some cases
61. Symptoms include pain in the right
hypochondrium ,hepatic enlargement and
ascites
In some cases the tumour gives rise to
systemic manifestations including
polycythemia, carcinoid syndrome
,hypoglycaemia and hypercalcaemia
Raised alpha-fetoprotein is present in 60-70%
of cases
62. HEPATIC METASTASIS
90% of hepatic tumours are metaststic from
primary in the gastrointestinal tract
,pancreas,lungs and breast
The most common are secondary hepatic
deposits from colorectal cancer
Morphologically on laparoscopic inspection
secomdary hepatic tumours may be
1- discretely nodular : (single or muliple)
2-miliary: widespread small seedling deposits
63. TREATMENT OF HEPATIC
TUMOURS
Hepatocellular carcinoma
Only patients who are not jaundiced ,have no
evidence of disease elsewhere (including
hepatic nodes) and are fit with good liver
functions are suitable for hepatic resection
Hepatectomy is not usually possible in
patients who develop the disease on a
backgroud of cirrhosis ,treatment is by in situ
ablation or embolization
64. Secondary tumours
usually from colorectal cancer are a much
more common problem
There is a definite place for surgical resection
if the disease is confined to one side and there
are no more than 3 deposits
The most imortant factor infuencing outcome
after surgical resection is a tumour free margin
of at least 1.5 cm
65. Systemic chemotherapy with high dose 5FU
with folinic acid induces disease regression in
30% of cases
There is no evidence that regional hepatic
intra-arterial chemotherapy is any more
effective than systenic chemotherapy
66. Only discretely nodular disease is potentially
curable by surgical resection
Only 5% of patients with hepatic metastasis
are suitable for this treatment
Palliation can be obtained by systemic
chemotherapy and by insitu ablation
techniques provided that the extent of hepatic
involvement is <25%
67. IN SITU ABLATION
In situ ablation either laparoscopic or image –
guided can be achieved by:
1-alcoholinization (small lesions <2 cm)
2-cryosurgery with high eficiency liquid
nitrogen
3-radiofrequency thermal ablation
4-interstitial laser hyperthermia
68. The advantage of in situ ablation is that it can
be repeated if new lesions or recurrence at
the treated sites detected on follow up
The early results of a combination of in situ
ablation with systemic chemotherapy look
very promising
69. 5-BENIGN BILE DUCT STRICTURES
1-Iatrogenic bile duct injury during
cholecystectomy
2-the constriction and compression of the
intrapancreatic segment of the CBD by the
pseudotumour of chronic pancreatitis
3-parasitic infestation of the biliary tract
4-multiple strictures of sclerosing cholangitis
71. SCLEROSING CHOLANGITIS
Is arare chronic disease characterized by fibrous
thickening of the intrahepatic or extrahepatic bile
ducts often associated with multiple strictures
CAUSES
PRIMARY SCLEROSING CHOLANGITIS: the
exact cause of which remains unknown ,probably
an autoimmune disease
SECONDARY TO :ductal stones,congenital lesions
or operative trauma
72. PRESENTATION
the disease is 2-3 times more common in men
than in women
Symptoms include malaise ,jaundice,abdominal
pain ,anorexia,weight loss ,fever,pruritis
About one third of cases are associated with
chronic inflammatory bowel disease (U.C. or
C.D.)
Hepatitis virus does not cause primary
sclerosing cholangitis
73. DIAGNOSIS
The diagnosis of primary sclerosing cholangitis is based on
clinical suspicion confirmed by cholangiographic demonstration of
multiple strictures separated by segments of ducts of normal or
increased diameter (beaded apperance)
Liver biopsy confirm the diagnosis
DIFFRENTIAL DIAGNOSIS.
The clinical and histologic patterns of S.C. overlap those of
primary biliary cirrhosis ,however the latter disease typically affects
middle aged women with keratoconjunctivitis
sicca,hyperpigmentation and high titres of A.M.A.
Cholangiography allows diffrentiation as primary biliary cirrhosis
never involves extrahepatic ducts
74. TREATMENT(controversial)
If a major stricture involves extrahepatic duct (bypass
procedure)
Other cases have been treated successfully by T.tube
drainage of the C.B.D. and by stenting of strictures
High dose steroids can be effective in relieving the fibrous
strictures
The oral adminstration of ursodiol shows promise ,it
reduces serum bilirubin , decreases clinical jaundice
,decreases serum transaminase levels and improve
symptoms
Liver transplantation is the only effective treatment of end
stage liver disease
75. PROGNOSIS
Some patients die from liver failure within
months of diagnosis
Others may live relatively symptom free for
many years
10% of patients with sclerosing cholangitis
will develop bile duct carcinoma
