Cardiovascular disease

People with severe obesity often experience fat surrounding the heart muscle, making it difficult for the heart to contract. In addition, the fat surrounding the heart can also compress the coronary artery (the arteries that supply blood to the heart), preventing blood from circulating to the heart. Anemia in the heart for a long time causes heart failure, life-threatening myocardial infarction.

High blood pressure

Conception leads to female infertility.

In men, obese people have 50% lower testosterone levels than normal people (testosterone is a determinant of men’s sexual ability), causing them to lose their libido, leading to impotence, disorder, erection and infertility.


Obesity is a risk factor for colon cancer in men and women, rectal and prostate cancer in men, and gallbladder and uterine cancer in women.
