Unexplained weight loss causes
Losing weight without dieting or exercise is a pleasant surprise, right? Think again. It might not necessarily be a positive sign. No! This is not to scare you, but instead to make you aware that unexplained or sudden weight loss could be a sign of a disease. This is especially true for those experiencing weight loss of more than 5 percent of their body weight within a span of 6 to 12 months, without resorting to dieting or exercising. It is advisable to see your doctor in such a situation.
Below are 6 causes for unexplained weight loss:
1) Overactive Thyroid: The condition in which your thyroid gland makes too much thyroid hormone is known as hyperthyroidism. In other words, the thyroid glands are overactive. These hormones control many functions in the body, including metabolism, which is why an overactive thyroid gland will burn many calories, resulting in weight loss.
2) Diabetes: If you have type 1 diabetes, your immune system starts attacking cells in your pancreas that produce insulin, without which your body becomes incapable of using glucose for energy, resulting in high blood glucose. The kidneys remove this unused glucose in the body and as the sugar leaves your body, so do calories. Reduction in calories leads to weight loss.
3) Rheumatoid Arthritis: This is an autoimmune disease that makes your immune system attack the lining of your joints which lead to inflammation. Chronic inflammation can speed up metabolism and reduce overall weight.
4) Tuberculosis: Another cause of unexplained weight loss is tuberculosis (TB), a contagious condition that usually affects the lungs. Weight loss and decreased appetite are major symptoms of TB, but the reasons aren’t fully understood.
5) Depression: Interestingly, depression affects the same part of the brain that controls appetite and therefore depression can lead to poor appetite which will eventually result in weight loss.
6) Cancer: Cancer increases inflammation which promotes muscle wasting and disrupts appetite-regulating hormones. One of the first signs of cancer may be unexplained weight loss of 10 pounds or more. This is common with cancers of the pancreas, lung, stomach, and esophagus.
