Killer of your Health

Obesity is a chronic illness in which person accumulates excess fat, which can jeopardize health. Obesity is the result of an increase in the size or percentage of fat cells in the body. When a person gains weight, these fat cells first grow in size and then in number.

Since obesity is a chronic illness, its symptoms (called co-morbidities)) develops gradually. In its early stages, obesity can make it hard to walk and cause back pain, fatigue, skin conditions & shortness of breath. If left untreated, obesity has a tendency to worsen. When obesity crosses the line into morbid obesity, it can lead to life threatening illness such as type 2 diabetes, high blood pressure, certain forms of cancer, high cholesterol and sleep apnea. The only way to prevent further development of the symptoms is to achieve lasting weight loss.

Mortality (Early death): Obesity is proven risk factor for early death from number of diseases increase as BMI increases. This risk is more in person who remains overweight for longer period of time.

Lower quality of life: Obesity affects social, psychological and financial aspect of person. Obese individuals are routinely discriminated against in terms of employment. Severely obese individuals are thought of by much of the public as being lazy and lacking self-discipline. Psychologic diseases such as depression therefore have an extraordinarily high incidence in this population compared with the general public. Poor self-image is almost universal among these individuals as well.


Normal Digestive System

To better understand how weight loss surgery works, it is important to understand how your gastrointestinal tract functions. As the food you consume moves through the gastrointestinal tract, various digestive juices and enzymes are introduced at specific stages that allow absorption of nutrients.

What are the side effect or complications after Bariatric Surgery

Bariatric surgery is as safe as gallbladder or appendix surgery in the hands of an expert and experienced doctor.

Bariatric surgery is a safe and effective treatment for obesity, but like any surgery, it does carry some risks and potential complications. Here are some of the common side effects and complications that can occur after bariatric surgery:

Complications during or after Bariatric Surgery, include:

  • Complications related to Anaesthesia: Reactions to drugs used (anesthesia) or other medicines. Although rare, these can be serious because they can cause dangerously low blood pressures.
  • Complications related to underlying medical illness like heart disease, diabetes, kidney disease, obesity, malnutrition.
  • Complications related to Specific Operations, Bariatric Surgery:
    •  Infection of wound: 1-2%
    • Bleeding: 0.1 – 1 %
    • Blood clot in legs: 0.5-1%
    • Vitamin deficiency: 10-30%
    • Ulcer: 1-5%
    • Weight Regain: 5-10%
  • Conversion to open surgery: In a small number of patients the laparoscopic method is not feasible because of the inability to visualize or handle the organs (stomach or intestine) effectively. The decision to convert to an open procedure is strictly based on patient safety.

It’s important to remember that the risks and complications of bariatric surgery are relatively low, and the benefits of the procedure typically outweigh the risks.

Most patients experience significant weight loss and improvement in obesity-related health problems after bariatric surgery.

What are the complications of Obesity, if treatment is delayed for some or other reasons?

  1. Type 2 diabetes:
  2. Cardiovascular disease: Obesity increases the risk of developing heart disease and stroke (Paralysis).
  3. High Blood Pressure: Excess body fat can put a strain on the heart and blood vessels, leading to high blood pressure, high cholesterol, and other cardiovascular problems.
  4. Sleep apnea: Obesity is a leading cause of sleep apnea, a condition in which a person’s breathing repeatedly stops and starts during sleep.
  5. Joint problems: Obesity puts extra stress on the joints, particularly the knees and hips. Over time, this can lead to joint pain, osteoarthritis, and other joint problems.
  6. Mental health problems: Obesity can have a negative impact on mental health, leading to depression, anxiety, and other mental health problems.
  7. Cancer: Obesity is linked to an increased risk of about 12 types of cancer, including breast, colon, and prostate cancer.

Why I need Weight Loss treatment or surgery?

Weight loss treatment or surgery may be recommended in certain situations where other methods of weight loss, such as diet and exercise, have not been effective or when obesity-related health conditions pose significant risks to your health. Here are some reasons why weight loss treatment or surgery may be necessary:

  1. Obesity-related health conditions: Obesity is associated with a higher risk of developing various health conditions, including type 2 diabetes, high blood pressure, heart disease, sleep apnea, certain cancers, and joint problems. If you have these conditions or if your health is significantly impacted by obesity, weight loss treatment or surgery may be recommended to improve your overall health and reduce the risk of complications.
  2. Failed attempts at weight loss: If you have made consistent efforts to lose weight through lifestyle modifications, such as diet and exercise, but have not achieved significant or sustainable weight loss, weight loss treatment or surgery may be considered as an alternative or additional approach to help you reach a healthier weight.
  3. Higher Body mass index (BMI): In cases of severe obesity, where the body mass index (BMI) is 40 or higher, or when BMI is between 35 and 39.9 accompanied by obesity-related health conditions, weight loss surgery may be recommended. Surgery can provide significant and sustained weight loss, leading to improvements in overall health and quality of life.
  4. Impact on mental and emotional well-being: Obesity can have a significant impact on mental and emotional well-being, leading to low self-esteem, depression, anxiety, and social isolation. Weight loss treatment or surgery can help improve body image and psychological well-being, promoting a better quality of life.
How I know that I am suffering from Obesity ?

Determining whether you are suffering from obesity involves assessing your body weight in relation to your height and evaluating other factors related to your health. Here are some common methods used to identify obesity:

  • Body Mass Index (BMI):
    • BMI is a widely used tool to assess body weight relative to height.
    • It is calculated by dividing your weight in kilograms by the square of your height in meters (BMI = weight in kg / (height in meters)^2). The World Health Organization (WHO) categorizes BMI ranges as follows:
      1. Underweight: BMI < 18.5
      2. Normal weight: BMI 18.5 – 24.9
      3. Overweight: BMI 25 – 29.9
      4. Obesity (Class 1): BMI 30 – 34.9
      5. Obesity (Class 2): BMI 35 – 39.9
      6. Severe obesity (Class 3): BMI ≥ 40
  • Waist Circumference:
    • Measuring your waist circumference can provide additional information about abdominal obesity, which is associated with an increased risk of certain health conditions.
    • Generally, a waist circumference above 40 inches (102 cm) for men and 35 inches (88 cm) for women is considered indicative of abdominal obesity.
  • Health Assessment:
    • Assessing your overall health and the presence of obesity-related conditions can also indicate if you are suffering from obesity.
    • Conditions commonly associated with obesity include type 2 diabetes, high blood pressure, high cholesterol, sleep apnea, joint problems, and heart disease.
    • If you have these conditions or if your healthcare provider diagnoses you with obesity-related health issues, it suggests the presence of obesity.
