Obesity definition

The definition of an obese person is a person who has excess fatty tissue and a BMI value of more than 30. BMI is an indicator that measures weight compared to height, as excess fatty tissue may have serious health consequences, such as: diabetes, and high blood pressure. High level of fats in the blood.

Obesity is one of the most common medical conditions in Western society today and one of the most difficult in terms of treating and combating obesity. Relatively little progress has been made in treating obesity except for lifestyle changes, but much information has been collected regarding the medical consequences of obesity.

Obesity causes

The main causes of obesity include the following :

Physical inactivity

Inactive people burn fewer calories than active people, as the National Health and Nutrition Examination Survey showed a strong relationship between physical inactivity and weight gain in both sexes.


Overeating leads to weight gain, especially if the diet is high in fat.

Foods that are high in fat or sugar, such as fast food, fried foods, and sweets, have a high energy density, meaning many calories in a small amount of food.


A person is more likely to become obese if one or both parents are obese, as genetics also influences the hormones involved in regulating lipids.

One genetic cause of obesity is a lack of leptin, a hormone produced in fat cells and the placenta. Leptin controls weight by sending signals to the brain to eat less when body fat stores are too high.

If for some reason the body cannot produce enough leptin or the leptin cannot send a signal to the brain to eat less food, this control is lost and obesity occurs.

Follow a diet rich in simple carbohydrates

The role of carbohydrates in weight gain is unclear. Carbohydrates increase blood glucose levels, which in turn stimulate the pancreas’ secretion of insulin, which promotes the growth of fatty tissue and can cause weight gain.

Some scientists believe that simple carbohydrates, such as: sugars, fructose, sweets, and soft drinks contribute to weight gain. Because they are faster absorbed into the bloodstream than complex carbohydrates, such as: pasta, brown rice, grains, and vegetables.

Eating frequency

The relationship between frequency of food intake and weight is somewhat controversial, there are many reports of overweight people eating less than people of normal weight.

Scientists have observed that people who eat small meals four or five times a day have lower cholesterol levels and lower and more stable blood sugar levels than people who eat less frequently, that is, two or three large meals a day.

One possible explanation is that frequent small meals produce stable levels of insulin, while large meals cause a significant spike in insulin after meals.


Medications associated with weight gain include some antidepressants, anticonvulsants, some diabetes medications, some hormones such as oral contraceptives, and most corticosteroids such as prednisone.

Some high blood pressure medications and antihistamines cause weight gain. The cause of weight gain varies with medications for each medication. If this is a concern for you, you should discuss your medications with your doctor rather than stopping medication. Because this may have dangerous effects.

psychological factors

For some people, emotions affect eating habits, many people eat excessively in response to emotions, such as: boredom, sadness, stress, or anger, while most people who are overweight do not suffer from psychological disorders more than other people. of normal weight.

About 30% of people who seek treatment for serious weight problems have difficulties with binge eating.

Obesity treatment

There are some procedures that can be followed to treat obesity, including the following :

  • Increase physical activity (at least 30 minutes a day).
  • Adopt a healthy balanced diet rich in vegetables, fruits, and whole grains, and reduce the intake of fats, sugars, and salt.
  • Treating diseases and health problems that cause obesity.
  • Take pharmacological drugs, but you must consult a doctor because there are many unlicensed drugs that may have dangerous side effects.
  • The use of the LPG device, which is a device used to move the fat under the skin without surgery, as it is used in the form of multiple sessions to treat simple cases of obesity.
  • The use of Mesotherapy, which may be used in some centers to treat obesity in simple cases.
  • Surgical intervention, which may be used if all methods and solutions to treat obesity have been exhausted
  • Liposuction, which is carried out using a special device to remove fat from different areas of the body, through a very small incision of several millimeters in length, and may be performed under local or general anesthesia, depending on the amount of fat to be removed, and the patient’s desire or tolerance . Also, fat may be removed either in one session or in several stages and sessions.
