Why did my father lose weight after an angioplasty?

Q: My father, 67 years old, had blockages removed through angioplasty but after angioplasty he lost around 16 kg. Why is this so? How can he regain the weight?

A:The most common cause of such weight loss is the anxiety associated with the procedure as well as a dramatic change in the dietary habits. The weight should come back to normal levels once the daily activities and the diet stabilise. If it persists, then some investigations need to be done.
