Are you Struggling to Control of your Diabetes and Weight?
People who are overweight or obese are more prone to developing Type 2 diabetes. Those who have Type 1 and Type 2 diabetes with weight problems struggle to control their blood sugar levels. Research shows that people with diabetes find it more difficult to lose weight than those without diabetes.
Weight loss significantly improves blood sugar control and also reduces the risk of getting complications from diabetes. However, whilst attempting to lose weight, people with diabetes find it hard to restrict their intake of food since eating less may trigger hypoglycaemia (low blood sugar). All these facts explain the need for specialist input in management of weight in people with diabetes.

Preventing diabetes and obesity in mental health disordersHealthXn
Diabetes is common in people with mental health disorders. This presentation discusses why and what therapies may worsen the disorder and how to prevent obesity and diabetes
DEFINITION AND MEASUREMENT Obesity is a state of excess adipose tissue mass. Although often viewed as equivalent to increased body weight, this need not be the case—lean but very muscular individuals may be overweight by numerical standards without having increased adiposity.
Body mass index (BMI), which is equal to weight/height2 (in kg/m2 )
Body weights are distributed continuously in populations, so that choice of a medically meaningful distinction between lean and obese is somewhat arbitrary. Obesity is therefore defined by assessing its linkage to morbidity or mortality
Similar to obesity diabetes and metabolic syndrome (20)

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!

Overall life span (LS) was 1671.7±1721.6 days and cumulative 5YS reached 62.4%, 10 years – 50.4%, 20 years – 44.6%. 94 LCP lived more than 5 years without cancer (LS=2958.6±1723.6 days), 22 – more than 10 years (LS=5571±1841.8 days). 67 LCP died because of LC (LS=471.9±344 days). AT significantly improved 5YS (68% vs. 53.7%) (P=0.028 by log-rank test). Cox modeling displayed that 5YS of LCP significantly depended on: N0-N12, T3-4, blood cell circuit, cell ratio factors (ratio between cancer cells-CC and blood cells subpopulations), LC cell dynamics, recalcification time, heparin tolerance, prothrombin index, protein, AT, procedure type (P=0.000-0.031). Neural networks, genetic algorithm selection and bootstrap simulation revealed relationships between 5YS and N0-12 (rank=1), thrombocytes/CC (rank=2), segmented neutrophils/CC (3), eosinophils/CC (4), erythrocytes/CC (5), healthy cells/CC (6), lymphocytes/CC (7), stick neutrophils/CC (8), leucocytes/CC (9), monocytes/CC (10). Correct prediction of 5YS was 100% by neural networks computing (error=0.000; area under ROC curve=1.0).
CDSCO and Phamacovigilance {Regulatory body in India}NEHA GUPTA
The Central Drugs Standard Control Organization (CDSCO) is India's national regulatory body for pharmaceuticals and medical devices. Operating under the Directorate General of Health Services, Ministry of Health & Family Welfare, Government of India, the CDSCO is responsible for approving new drugs, conducting clinical trials, setting standards for drugs, controlling the quality of imported drugs, and coordinating the activities of State Drug Control Organizations by providing expert advice.
Pharmacovigilance, on the other hand, is the science and activities related to the detection, assessment, understanding, and prevention of adverse effects or any other drug-related problems. The primary aim of pharmacovigilance is to ensure the safety and efficacy of medicines, thereby protecting public health.
In India, pharmacovigilance activities are monitored by the Pharmacovigilance Programme of India (PvPI), which works closely with CDSCO to collect, analyze, and act upon data regarding adverse drug reactions (ADRs). Together, they play a critical role in ensuring that the benefits of drugs outweigh their risks, maintaining high standards of patient safety, and promoting the rational use of medicines.

2. Obesity: definition
• Chronic disease characterized by
accumulation of fat. Obesity is defined as a
condition when ideal body weight is exceeded
by 20%
• Medical condition responsible for serious co-
morbidity and mortality.
3. Psychosocial consequence
• Economical impact of obesity
• Prejudice and Discrimination (pay double fare
in matatus)
• Considered lazy, incompetent and more often
absent due to illness
• Confronted with more problems at job
application :
–Very few executive managers with overweight in
the US
6. What causes Obesity?
• Genetic predisposition
• Disruption in energy balance
• Environmental and social factors
7. • An individual may have a genetic
predisposition to become obese, but will only
become obese given the right environmental
influences.
• It has been suggested that up to 50% of the
variability in body weight is governed by
genetic factors.
• Some 360 genes have now been identified
and related to the development of obesity
although some of them may have a very small
role.

16. The Metabolic Syndrome (MS)
•Is a multiplex risk factor for cardiovascular disease
and type 2 diabetes’
• Reflects the clustering of individual risk factors due to
abdominal obesity and insulin resistance.
•This multiplex comprises the following interrelated
metabolic risk conditions:
Atherogenic dyslipidemia, glucose intolerance, elevated
blood pressure, proinflammatory state, and prothrombotic
state.
•Atherogenic dyslipidemia is itself an aggregate term comprised
of elevated fasting and nonfasting triglycerides, elevated VLDL,
reduced HDL, and an atherogenic small dense LDL phenotype

Most frequently affects children and adolescents.
Symptoms include excessive thirst, excessive urination,
weight loss and lack of energy.
Daily insulin injections required for survival.
Type 2 diabetes
Occurs mainly in adults.
Usually people have no early symptoms.
People may require oral hypoglycaemic drugs and may also
need insulin injections at later stages.

35. How to test
Testing for diabetes
• Fasting morning blood glucose is the best
initial test.
• Urine glucose and HbA1C should not be used
for diagnosis.
35GKM/MLS3202/LECT 02/2014
36. People with symptomatic
hyperglycaemia
•Symptomatic hyperglycaemia may have an acute onset,
usually in younger people with type 1 diabetes, or a more
insidious onset, usually in older people with type 2 diabetes.
•The usual symptoms of hyperglycaemia are thirst, polyuria
and weight loss but hyperglycaemia can also cause fatigue,
lack of energy, blurring of vision or recurrent infections, such
as candida.
For people with symptomatic hyperglycaemia,
a single fasting glucose of ≥ 7.0 mmol/L
OR
a random glucose of ≥ 11.1 mmol/L
is diagnostic of diabetes.

40. Gestational diabetes mellitus
Gestational diabetes mellitus (GDM) increases the risk of many
foetal and maternal complications in pregnancy and the
development of type 2 diabetes later in life (Kjos, 1999).
Screening is recommended for all women between 24 - 28
weeks gestation.
Screening for GDM using 50 gram load (1 hr OGGT)
If the one hour blood glucose is ≥ 7.8 mmol/L, a two hour OGTT
is performed.
OGTT for diagnosis of GDM
A fasting glucose ≥ 5.5 and/or a 2 hour value
≥ 9.0 mmol/L is diagnostic of GDM.

42. Types of gestational diabetes
Type A1
– Reveals altered finding during oral glucose tolerance test (OGTT),
but with normal blood glucose levels with fasting and after two
hours with meals.
– With this stage of gestational diabetes, diet modification is
enough to manage the increased glucose levels.
• Type A2
– Reveals altered finding during oral glucose tolerance test (OGTT),
it also has elevated glucose levels even during fasting and/ or
during after meals.
– Apart from modification of lifestyle and diet, adjunct therapy with
insulin and other diabetes medications are indicated and
necessary.

44. HbA1C and Target levels
Any sustained reduction of HbA1C is worthwhile
because there appears to be a direct relationship
between cardiovascular risk and HbA1C.
The goal is to achieve an HbA1C as low as possible,
preferably less than 7.0%, without causing
unacceptable hypoglycaemia.
HbA1C > 8 mmol/L is a sign of inadequate control for
most people.
HbA1C targets need to be indiviadualized, taking into
consideration factors such as the patient’s age .
Stable diabetes Test six monthly
Changes in treatment
Test no more than three
monthly

45. Self monitoring blood glucose (SMBG)
People who take insulin should regularly self monitor
blood glucose.
For people with non-insulin treated type 2 diabetes
testing is most useful if patients use the results to learn
and alter behaviour, or medication.
“...SMBG is most useful if patients use the results to learn, as part of an
overall diabetes education package….”

46. Laboratory tests to prevent and delay
complications of diabetes
People with diabetes usually die from
macrovascular complications of their
diabetes; namely cardiovascular
disease.
This is influenced by all of the
commonly recognised risk factors for
cardiovascular disease as well as
glycaemic control.
Fasting lipid levels are measured
three monthly until stable and then 6
- 12 monthly thereafter.
It is important that management
should be individualised

49. • Glycosylation damages blood vessels
• Mostly affects blood vessels & nerves
– glycolated proteins in vessel wall makes it stiffer &
less elastic
– in large vessels, accelerates atherosclerosis
– in small vessels, slows blood flow & diffusion

50. • Vascular disease
• impairs blood flow causing ischemia (restriction in
blood supply to tissues) & infarction
• high incidence of
– Myocardial infarction (MI)
– stroke
– lower limb gangrene
– microvascular disease
• characterized by hyaline arteriolosclerosis (refers to
thickening of the walls of arterioles)
• leads to diabetic nephropathy & diabetic retinopathy

Experts now generally believe that both are important in the development of obesity; an individual may have a genetic predisposition to become obese, but will only become obese given the right environmental influences.
It has been suggested that up to 50% of the variability in body weight is governed by genetic factors.
Some 360 genes have now been identified and related to the development of obesity although some of them may have a very small role.
In the ‘eat to live’ mode, with energy intake balanced by energy expenditure, we could be weight stable.
In the ‘live to eat’ mode, energy intake too often exceeds energy expenditure with the result that there is an increasing tendency towards becoming obese.
A 70 kg person at 70 years of age expends considerably less energy than a 70 kg person at 25 years of age.
The main differences are in the absence of both occupational activity and extreme physical exertion.
However, energy intake does not generally fall as rapidly as energy expenditure, perhaps due to a lifetime habit of eating very palatable food.
Therefore, the tendency over time is for body weight to increase as we get older.
James, Ralph and Ferro-Luzzi, 1989
While the gene pool alters slowly, over many thousands of years, our environment has changed dramatically in recent decades.
Therefore, the recent rise in obesity is most likely due to changes in environmental factors, particularly to changes in our dietary energy intake.
Dietary fat in particular, appears to be the main problem.
Fat is associated with a higher energy content than other foods
Fat can be stored to an enormous extent in our bodies
Fat does not suppress hunger.
Consequences of obesity
The slide illustrates the most common co-morbidities and risk factors associated with obesity. These range from type 2 diabetes, osteoarthritis, cancer of the breast and prostate, major cardiovascular disease, stroke and respiratory disease to gallstones and gout. In short, obesity predisposes patients to a variety of diseases and, accordingly, should be considered by the medical profession as a serious, potentially life-threatening condition rather than an affliction brought on by lack of self-control.
But obesity also has other, frightening consequences in addition to type 2 diabetes.
This picture is from a paediatric ophthalmology journal and demonstrates blindness in a child as a result of fat infiltration in the eyelids.

The latest classification of the metabolic syndrome includes a reduction in the fasting glucose level from &gt;110 mg/dL to &gt; 100 mg/dl.
Among those who have a greater number of metabolic syndrome criteria, there is an increased risk of death from cardiovascular disease.
Patients with the metabolic syndrome can decrease their risk of developing diabetes with a program targeted at weight loss, reduced calorie intake, reduced saturated fat, and increased physical activity (30 minutes/day).
The Diabetes Prevention Program demonstrated that weight loss and physical activity (averaged to 22 minutes/day) reduced the incidence of diabetes to a greater extent than medication alone. This study, along with the Finish Diabetes Prevention Study, highlight the importance of structured lifestyle modifications in at risk individuals to reduce the risk of developing diabetes.
