Q: I am on a weight loss programme. One of the tools of the programme involves the use of a German machine, where heat is applied on the patient's body with consequent sweating. It is probably draining the lymphatic system. I have suffered number of loose motions approximately 8-10 times a day, subsequently along with slight weakness and loss of appetite. There is no infection or gastroenteritis. Are these effects normal to such treatment? What are the future risks and likely side effects? Do they vary greatly from individual to individual?

A:I suggest you stop your treatment immediately. You have suffered a side effect due to excessive heating of the tissues leading to a metabolic disorder. There could be other side effects such as your vasomotor centre could be affected due to the rise in temperature leading to dilatation of your blood vessels resulting in a fall of blood pressure and related symptoms. I suggest you should go in for prompt medical advice.
