Weight loss refers to unintentional reduction in weight without changing the diet or exercise routine. It can be caused by stressful events, illness (e.g. diarrhoea, cancer), infection (e.g. worm infestation), certain medications, malnutrition or combination of these factors. You may notice fatigue, change in the fitting of your cloths or shape of face. The treatment depends on identifying and treating the root cause of unintentional weight loss.
