Obesity is one of the most serious risks for several health problems. Furthermore, apart from the effect of obesity on your physical health, it has also bad psychological impacts, loss of confidence and self-esteem. Obese persons also may suffer from low social activities as they are afraid of being criticized by others because of their appearance. This, in turn, can cause more psychological disorders such as social phobia, depression and anhedonia, a condition of feeling lonely and loss of hope in life.
Obesity can be defined as having a body mass index (BMI) of 30 or more.
The more fats you have, the greater the risk of suffering from the following conditions:
1# Cardiovascular problems:
Overweight can cause high levels of cholesterol in the body which in the long term may lead to atherosclerosis, high blood pressure, stroke, and cardiac diseases. Obesity is also a part of the metabolic syndrome which puts individuals at more cardiovascular risks and sudden cadriac death. Thus, it is always advised for cardiac patients to lose weight to decrease the chance of developing more heart complications.
2# Gallbladder disease:
One great risk for having gallstone is obesity. Several studies showed that the prevalence of having gallstones is higher in people with more BMI. interestingly, losing weight at a high rate can also raise the risk of gallstones, which is believed to be due to supersaturation of the bile with cholesterol. Therefore, It is always recommended to lose weight at a rate of about 1 bound/week to lower the incidence of having gallstones.
3# joint disease:
Carrying extra weight put more pressure on your joints particularly knees, hips, and lower back. This makes you more prone to develop joint problems such as osteoarthritis, a condition of joint cartilages degradation causing friction and inflammation in the joint space. Moreover, it was found that gout, a joint disease due to uric acid deposition in the joints, is more common in obese people.
4# Type 2 Diabetes:
In addition to Family history and genes, Obesity and decreased activities are popular risks for developing diabetes type 2. Extra fats decrease the sensitivity of cells to insulin. As a result, the level of blood glucose rises and gradually insulin may become ineffective at all. Overweight and unhealthy diet habits can also contribute to a reduced insulin secretion by the pancreas, which is considered a late stage of type 2 diabetes when the patient should take insulin treatment.
Recent researches showed that having high Body Mass Index (BMI) increases the risk of many adult cancers. The link between cancer and obesity isn’t clearly explained. However, it may be due to the release of hormones from fat cells that stimulate abnormal cell growth, raising the possibility to have cancer.
6# Liver diseases:
Excessive fats in the body can cause fatty liver diseases or non-alcoholic steatohepatitis (NASH). This condition is usually asymptomatic and can be discovered accidentally by ultrasound, but on the long-term over accumulation of fats in the liver may make hepatocytes more sensitive to endotoxins and predispose to more serious liver problems such as liver cirrhosis and even cancer.
