Infections such as HIV may also lead to weight loss. Hormonal disruptions, such as an overactive thyroid or hyperthyroidism may also exhibit as weight loss.
Apart from the unintentional weight loss, one can also lose weight intentionally. To look more slim and beautiful, many people are reducing their weight. But in the effort to improve health and fitness, one can develop serious health issues.
