I'm a man of 76 yrs, having copd (2 yrs), causing weight loss 6 kg & muscle wasting within 4 months. Loss of weight & muscle is common in copd-- but such abrupt loss aims at something else. Is it testosterone imbalance. My testosterone level is 38.10 nmol/l, reference range being 4.94 nmol/l to 32.01 nmol/l. What should I do?
