Effects of Obesity
Laziness is one of the consequences of obesity which leads to unproductiveness. Obesity causes diabetes, and the body may become resistant to insulin. Adults are more vulnerable to this—the developed resistant lead to a high level of blood sugar, which is fatal.
With an increase in body fat, the body requires more nutrients and oxygen to support. The blood transports it through blood vessels to various parts of the body. The heart starts pumping more blood with an increase in pressure on blood vessels, leading to hypertension. The increased heart rate is also dangerous due to its inability to supply blood to various parts, which ultimately leads to heart failure.
It also leads to respiratory disorders as obese people have reduced lung capacity. These people are at higher risk of respiratory infections like asthma. As the BMI increases, so does the risk of cancer which is a fatal disease.
Obesity also causes coronary heart disease. The arteries around the heart get blocked due to fatty deposits. It prevents the passage for blood flow.
Besides health complications, obesity also causes psychological effects. Obese people are prone to depression, social rejection, negative self-esteem, body shaming.
