Understanding Loss of Appetite
When someone experiences an unexplained loss of appetite, it could be a sign of an underlying health issue. In fact, this symptom was so closely associated with tuberculosis that the disease earned the nickname “consumption.” Patients suffering from tuberculosis often experienced extreme weight loss and wasting due to their lack of appetite.
A recent study conducted in the United States found that 45% of tuberculosis patients experienced weight loss, while 26% had anorexia or a complete loss of appetite. The researchers believe that changes in energy regulatory hormones may play a role in the wasting seen in these patients.
Interestingly, abnormal elevations of peptide YY, a hormone that is secreted by the small and large intestine and acts as an appetite suppressant, were discovered in some of the subjects in the study. This finding provides further insight into the mechanisms behind the loss of appetite experienced by individuals with tuberculosis.
Unintentional Weight Loss: A Possible Symptom of Tuberculosis
Unexplained weight loss can be attributed to various factors, one of which is a diminished appetite. However, it is important to note that weight loss can also occur independently. Studies have revealed that individuals with tuberculosis (TB) often undergo changes in the hormones responsible for regulating appetite. Astonishingly, approximately two-thirds of TB patients experience significant weight loss. This decline in weight can be attributed not only to a loss of appetite but also to the body’s increased energy expenditure as it fights off the infectious bacteria associated with TB.
