Excessive drinking may cause damage to the lungs, and people who drink heavily over a long period of time are more likely to develop tuberculosis, a disease caused by a bacteria attacking the lungs. According to a 2009 study, about 10% of all tuberculosis cases worldwide are linked to alcohol consumption.
Ulcers are relatively common among people who repeatedly drink heavily. An ulcer is a break in the membrane of an organ that hinders its proper functioning. Ulcers can be fatal if they are not caught early on because they can start bleeding internally.
23. Weight gain
Alcohol is a source of excess calories, but this is not the only way drinking can cause weight gain. Alcohol interferes with the body’s fat-burning functions.
Drinking supplies the body with calories but no nutrients. The calories from alcohol are the first to be burned by the body, delaying the fat-burning process, which comes after the body has burnt carbs and proteins for energy. This contributes to extra fat storage.
