During pregnancy, the female body undergoes many physiological changes to support the growing fetus. The genital organs like the uterus, cervix, and breasts enlarge and the vascularity increases. The cardiovascular system works harder - blood volume, heart rate, and cardiac output increase. Respiration also increases to supply more oxygen to the mother and fetus. Hormonal changes driven by the placenta result in further physical adaptations like skin pigmentation and breast development. These changes help create a healthy environment for the baby to develop over the 9 months of pregnancy.

Flu Vaccine Alert in Bangalore Karnatakaaddon Scans
As flu season approaches, health officials in Bangalore, Karnataka, are urging residents to get their flu vaccinations. The seasonal flu, while common, can lead to severe health complications, particularly for vulnerable populations such as young children, the elderly, and those with underlying health conditions.
Dr. Vidisha Kumari, a leading epidemiologist in Bangalore, emphasizes the importance of getting vaccinated. "The flu vaccine is our best defense against the influenza virus. It not only protects individuals but also helps prevent the spread of the virus in our communities," he says.
This year, the flu season is expected to coincide with a potential increase in other respiratory illnesses. The Karnataka Health Department has launched an awareness campaign highlighting the significance of flu vaccinations. They have set up multiple vaccination centers across Bangalore, making it convenient for residents to receive their shots.
To encourage widespread vaccination, the government is also collaborating with local schools, workplaces, and community centers to facilitate vaccination drives. Special attention is being given to ensuring that the vaccine is accessible to all, including marginalized communities who may have limited access to healthcare.
Residents are reminded that the flu vaccine is safe and effective. Common side effects are mild and may include soreness at the injection site, mild fever, or muscle aches. These side effects are generally short-lived and far less severe than the flu itself.
Healthcare providers are also stressing the importance of continuing COVID-19 precautions. Wearing masks, practicing good hand hygiene, and maintaining social distancing are still crucial, especially in crowded places.
Protect yourself and your loved ones by getting vaccinated. Together, we can help keep Bangalore healthy and safe this flu season. For more information on vaccination centers and schedules, residents can visit the Karnataka Health Department’s official website or follow their social media pages.
Stay informed, stay safe, and get your flu shot today!

Acute scrotum is a general term referring to an emergency condition affecting the contents or the wall of the scrotum.
There are a number of conditions that present acutely, predominantly with pain and/or swelling
A careful and detailed history and examination, and in some cases, investigations allow differentiation between these diagnoses. A prompt diagnosis is essential as the patient may require urgent surgical intervention
Testicular torsion refers to twisting of the spermatic cord, causing ischaemia of the testicle.
Testicular torsion results from inadequate fixation of the testis to the tunica vaginalis producing ischemia from reduced arterial inflow and venous outflow obstruction.
The prevalence of testicular torsion in adult patients hospitalized with acute scrotal pain is approximately 25 to 50 percent

Ethanol (CH3CH2OH), or beverage alcohol, is a two-carbon alcohol
that is rapidly distributed in the body and brain. Ethanol alters many
neurochemical systems and has rewarding and addictive properties. It
is the oldest recreational drug and likely contributes to more morbidity,
mortality, and public health costs than all illicit drugs combined. The
5th edition of the Diagnostic and Statistical Manual of Mental Disorders
(DSM-5) integrates alcohol abuse and alcohol dependence into a single
disorder called alcohol use disorder (AUD), with mild, moderate,
and severe subclassifications (American Psychiatric Association, 2013).
In the DSM-5, all types of substance abuse and dependence have been
combined into a single substance use disorder (SUD) on a continuum
from mild to severe. A diagnosis of AUD requires that at least two of
the 11 DSM-5 behaviors be present within a 12-month period (mild
AUD: 2–3 criteria; moderate AUD: 4–5 criteria; severe AUD: 6–11 criteria).
The four main behavioral effects of AUD are impaired control over
drinking, negative social consequences, risky use, and altered physiological
effects (tolerance, withdrawal). This chapter presents an overview
of the prevalence and harmful consequences of AUD in the U.S.,
the systemic nature of the disease, neurocircuitry and stages of AUD,
comorbidities, fetal alcohol spectrum disorders, genetic risk factors, and
pharmacotherapies for AUD.
NVBDCP.pptx Nation vector borne disease control programSapna Thakur
NVBDCP was launched in 2003-2004 . Vector-Borne Disease: Disease that results from an infection transmitted to humans and other animals by blood-feeding arthropods, such as mosquitoes, ticks, and fleas. Examples of vector-borne diseases include Dengue fever, West Nile Virus, Lyme disease, and malaria.
3. Vulva
Oedematous
More Vascular
Superficial varicosities may appear
specially in multiparae.
Labia minora are pigmented and
hypertrophied
4. Vagina
Vaginal walls become hypertrophied,
oedematous and more vascular.
Increased blood supply of the venous plexus
surrounding the walls
The length of the anterior vaginal wall is
increased.
Secretion becomes copious, thin and curdy
white
pH becomes acidic (3.5-6)
5. Uterus
Non-pregnant state weighs about 60gm, with a
cavity of 5-10 ml and measures about 7.5 cm in
length, at term, weighs 900-1000 gm and
measures 35cm in length
Changes occur in all the parts of uterus body,
isthmus and cervix.
Increase in growth and enlargement of the body
of the uterus
6. Changes in the muscles
(1)Hypertrophy and hyperplasia-occur under
the influence of the hormones-oestrogen
and progesterone
(2)Stretching: The muscle fibres further
elongate beyond 20 weeks due to
distension by the growing foetus. The
wall becomes thinner and at term,
measures about 1.5cm or less.
7. Arrangement of the muscle fibres
1)Outer longitudinal – follows a hood like
arrangement over the fundus; some fibres are
continuous with the round ligaments
(2) Inner circular – It is scanty and have sphincter
like arrangement around the tubal prifices and
internal os
(3) Intermediate – It is the thickest and strongest
layer arranged in criss-cross fashion through which
the blood vessels run.
Apposition of two double curve muscle fibres give
the figure of ‘8’ form, it called as living ligature.
8. Vascular system
Uterine artery diameter becomes double
Blood flow increases by eight fold at 20 weeks of
pregnancy.
Vasodilatation is mainly due to estradiol and
progesterone.
Veins become dilated and are valveless.
Numerous lymphatic channels open up.
Vascular changes are most pronounced at the
placental site
9. Weight
Weight is due to the increased growth of the
uterine muscles, connective tissues and
vascular channels
10. Shape
Non pregnant pyriform shape is maintained in
early months.
Becomes globular at 12 weeks.
As the uterus enlarge, the shape once more
becomes pyriform or ovoid by 28 weeks
Changes to spherical beyond 36th week
11. Position
Normal anteverted positions exaggerated up to
8 weeks
The enlarged uterus may lie on the bladder
Afterwards, it becomes erect, the long axis of the
uterus conforms more is a tendency of ante
version
Primigravidae with good tone of the abdominal
muscles, it is held firmly against the maternal
spine.
12. Contractions (Braxton-Hicks) : Irregular,
infrequent, spasmodic and painless without
any effect on dilatation of the cervix.
Endometrium : structural and secretory
activity of the endometrium
13. Isthmus
During the first trimester isthmus
hypertrophies and elongates to about 3
times its original length
Becomes softer
14. Cervix
Hypertrophy and hyperplasia of the elastic and
connective tissues
Vascularity is increased
Softening of the cervix (Goodell’s sign)
Squamous cells also become hyperactive
Mucosal changes simulate basal cell
hyperplasia or cervical intraepithelial neoplasia
(CIN)
Secretion is copious and tenacious –
physiological leucorrhoea of pregnancy
Becomes bulky
15. Fallopian Tube
Total length is increased
Tube becomes congested
Muscles undergo hypertrophy
16. Ovary
Growth and function of the corpus luteum
reaches its maximum at 8th week
Hormones-oestrogen and progesterone
secreted by the corpus luteum maintain
the environment for the growing ovum
Control the formation and maintenance of
decidua of pregnancy
Inhibit ripening of the follicles
17. BREAST CHANGES
Increased size of the breasts
Marked hypertrophy and proliferation of the
ducts (oestrogen and progesterone)
Vascularity is increased
The nipples become larger, erectile and deeply
pigmented
18. Sebaceous glands (5-15) become hypertrophied
and are called Montgomery’s tubercles
Outer zone of less marked and irregular
pigmented area appears in the second trimester
and is called secondary areola
Secretion (colostrum) can be squeezed out of
the breast at about 12th week
19. CUTANEOUS CHANGES
Face (cholasma gravidarum or pregnancy
mask)
an extreme form of pigmentation around the
cheek, forehead and around the eyes
20. Breast changes
Abdomen
• Linea nigra : a brownish black pigmented
area in the midline stretching from the
xiphisternum to the symphysis pubis
• Straie graviderum :slightly depressed
linear marks with varying length and
breadth found in pregnancy
21. HEMATOLOGICAL CHANGES
Blood volume
Due to increased vascularity of the enlarging
uterus, Blood volume is markedly raised during
pregnancy
The blood volume starts to increase from about
6th week, expends rapidly thereafter to
maximum 40-50% above the nonpregnant
level at 30-32 weeks
22. Plasma Volume
Starts to increase by 6 weeks
Rate of increase almost parallels to that of blood
volume
Reached to the extent of 50%
Total plasma volume increases to the extent of
1.25 litters
23. RBC And Haemoglobin
The RBC mass is increased to the extent of 20-
30%
Increase demand of oxygen transport during
pregnancy
Disproportionate increase in plasma and RBC
volume produces state of haemodilution (fall in
haemocrit)
Hb fall is about 2 gm.% from the non-pregnant
value.
24. Leucocytes And Immune System
In the second and third trimester, the action of the
polymorphoneuclear leukocytes may be
depressed, perhaps accounting for the increased
susceptibility of pregnant women to infection
Total plasma protein increases from the normal
180 gm. (non-pregnant) to 230 gm
Due to haemodilution(increase plasma volume),
the plasma protein concentration falls from 7 gm.%
to 6 gm.%
Blood Coagulation Factor Pregnancy is a
hypercoagulable state. Plasma fibrinogen (factor
1) increases from the third month of pregnancy
25. METABOLIC CHANGES
General Metabolic Changes
Total metabolism is increased due to the needs
of the growing fetus and the uterus
Basal metabolic rate is increased to the extent of
30% higher than that of the average for the non-
pregnant women.
Protein Metabolism
Positive nitrogenous balance throughout
pregnancy
At term, the fetus and the placenta contain about
500 gm. of protein and the maternal gain is also
about 500 gm.
26. Carbohydrate Metabolism
Insulin secretion is increased in response to
glucose and amino acids.
Hyperplasia and hypertrophy of beta cells of
pancreas.
Increased insulin level favours lipogenesis (fat
storage).This mechanism ensures continuously
supply of glucose to the fetus
Fat Metabolism
An average of 3-4 kg of fat is stored during
pregnancy mostly in the abdominal wall, breasts,
hips and thighs
27. Iron Metabolism
Iron is absorbed in ferrous form from duodenum
and jejunum and is released into the circulation
as transferrin
10 percent of ingested iron is absorbed
Total iron requirement during pregnancy is
estimated approximately 1000mg
In the absence of iron supplementation, there is
drop in haemoglobin, serum iron and serum
ferritin concentration at term pregnancy
28. Weight Gain
In early weeks, the patient may lose weight
because of nausea and vomiting
During subsequent months, the weight gain is
progressive until the last one or two weeks,
when the weight remains static
The total weight gain during the course of a
singleton pregnancy for a healthy woman
averages 11 kg
Distributed to 1 kg in first trimester and 5 kg
each in second and third trimester
29. The total weight gain at term is distributed
approximately as :
Reproductive weight gain
: 6 kg
Net maternal weight gain
: 6 kg
Fetus – 3.3 kg, placenta –
0.6 kg and liquor – 0.8 kg
uterus – 0.9 kg and
breast -0.4 kg,
accumulation of the fat
and protein – 3.5 kg
Increases in blood
volume – 1.3 kg
Increases in extracellular
fluid – 1.2 kg
30. Calcium metabolism and locomotor
system
Relaxation of pelvic ligaments and muscles
occurs because of the influence of estrogen and
relaxtin reaches maximum during last weeks of
the pregnancy
Increased lumber lordosis during later months of
the pregnancy due to enlarged uterus backache
and wadding gait
31. SYSTEMIC CHANGES
Respiratory System
Shape of the chest and the circumference increases
in pregnancy by 6 cm
Progressive increase in oxygen consumption, which
is caused by the increased metabolic needs of the
mother and fetus
The mucosa of the nasopharynx becomes
hyperaemic and oedematous
A state of hyperventilation occurs during
pregnancy leading to increase tidal volume
The woman feels shortness of breath
Pregnancy is a state of respiratory alkalosis
32. CARDIOVASCULAR CHANGES
The Heart :
muscle, particularly the left ventricles,
hypertrophies leading to enlargement of the
heart
The growing uterus pushes the heart upward
and to the left
During pregnancy the heart rate and stroke
volume (the amount of the blood pumped by
heart with each beat) increases due to the
increase blood volume and oxygen requirement
of the maternal tissues and growing fetus
33. Cardiac Output :
increases markedly by the end of the first
trimester.
In the third trimester, a rise, fall or no change at
all has been showed to occur, depending on
individual variables.
lowest in the sitting or supine position and
highest in the right or left lateral or knee chest
position.
The capacity of veins and venules increases.
Arterial walls relax and dilate due to the effect of
progesterone. The increase production of
vasodilator prostaglandin also contributes to
this.
34. Blood Pressure
During the mid-trimester, changes in blood
pressure may occur causing fainting
In later pregnancy, hypotension may occur in
10% of women in unsupported supine position.
This termed as “supine hypotensive
syndrome”
The pressure of gravid uterus compresses the
vena cava, reducing the venous return
Cardiac output is reduced by 25-30 percent and
the blood pressure may fall by 10-15 percent
35. Regional Distribution Of The Blood Flow
Uterine blood flow is increased from 50 ml per
minute in non-pregnant state about 750 ml near
term
Pulmonary blood flow (normal 6000ml/min) is
increased by 2500 ml per minute
Renal blood flow (normal 800 ml) increases by
400 ml per minute at 16th week remains at this
level till term
Heat sensation, sweating or stuffy nose
complained by the pregnant women can be
explained by the increased blood flow
36. Urinary System
• kidney
Dilatation of the ureter, renal pelvis and calyces. The
kidneys enlarge in length by 1 cm.
Renal plasma flow is increased by 50-75%, maximum
by the 16 weeks and is maintained until 34 weeks.
Thereafter it falls by 25%.
Glomerular filtration rate (GFR) is increased by 50%
all throughout the pregnancy
• Ureter
ureters become atonic due to high progesterone level.
Dilatation of the ureter above the pelvic brim with
stasis is marked on the right side specially in
primigravidae.
37. • Bladder
Increased frequency of micturition is noticed at
6-8 weeks of pregnancy which subside after 12
weeks and In late pregnancy, frequency of
micturition once more reappears due to
pressure on the bladder as the presenting part
descends down the pelvis.
Stress incontinence may observe in late
pregnancy due to urethral sphincter weakness
38. Alimentary System
Gums become congested and spongy and may
bleed to touch
Risk of peptic ulcer disease is reduced.
Atonicity of the gut leads to constipation
• Liver and gall bladder
Liver functions are depressed
High blood cholesterol level during pregnancy,
favour stone formation
39. NERVOUS SYSTEM
Temperamental changes are found during
pregnancy and in the puerperium
Nausea, vomiting, mental irritability and
sleeplessness are probably due to some
psychological background
Postpartum blues, depression or psychosis may
develop in a susceptible individual
40. CHANGES IN THE ENDOCRINE
SYSTEM
Placental Hormones
Placenta produces several hormones
The high levels of estrogen and progesterone
produced by the placenta are responsible for
breast changes, skin pigmentations and uterine
enlargement in the first trimester
Chorinonic gonadotrophin is the basis for the
immunologic pregnancy tests
Human placental lactogen stimulates the growth
of the breasts
41. Pituitary Hormones
The secretion of prolactin, adrenocorticotrophic
hormone, thyrotrophic hormone and
melanocyte-stimulating hormone increases
Follicle stimulating hormone and luteinzing
hormone secretion is greatly inhibited by
placental progesterone and estrogen.
The effects of prolactin secretion are suppressed
during pregnancy
Posterior pituitary gland releases oxytocin in
low-frequency pulses throughout pregnancy. At
term the frequency of pulses increases which
stimulates uterine contractions
42. Thyroid Function
Gland increases in size by about 13 percent due
to hyperplasia of glandular tissue and increased
vascularity
Increased uptake of iodine during pregnancy
Pregnancy can give the impression of
hyperthyroidism, thyroid function is basically
normal
The basal metabolic rate is increased mainly
because of increased oxygen consumption by
the fetus and the work of the maternal heart and
lungs
