Weight loss
In cancer, many events contribute to weight loss, and it is a very rapid and concerning type of weight loss that instead of being beneficial it becomes a significant health problem. Cancer cells feed off the nutrients our body normally uses to grow healthy and maintain weight. Anorexia leads patients to eat even less than they should. Hormonal and metabolic changes would increase calorie expenditure and contribute to weight loss. Therefore, it is difficult to control weight loss in cancer, and sometimes it is so rapid that not even nutritional supplements are able to improve the patient’s condition.
