###Human: Does low level of testosterone cause weight gain issues? ###Assistant: Hi.I have read through your query in detail. Please find my observations below. If obesity runs in your family, then that might have influenced your weight gain. Such weight gain is genetic and therefore if your parents and relatives have a tendency of obesity then it is genetic and no other test is required. In males, stress-related anxiety plays an important role in weight gain. Many men gain weight due to increased mental stress. If you have any such stressful factors causing your weight gain, then please do mind relaxation exercises and being happy and cheerful will help in weight management. Eating also influences weight gain. Even if you are strict with the food you eat, please eat multiple small meals instead of a few large meals. This will distribute the calories evenly and you will not over eat. You might have daily 2200 kcal diet with small meals every 3 - 4 hours. As per your reports (attachment removed to protect patient identity), your testosterone level is near the lower limit and this is also related to obesity. It should be at mid-level. If you balance your stress levels and have a good healthy diet then your testosterone might get back to the mid-range. However, please avoid taking testosterone supplement because it can be harmful and have long term side effects like hair loss. Please do exercises for 30 minutes everyday and yoga for 30 minutes. Please get detailed evaluation done for diabetes. This should include fasting blood glucose, post prandial blood glucose and HbA1c blood test. Genetic, stress, over eating or diabetes related weight gain. Life style changes, confirmation of any medical condition like diabetes and intake of low fat diet.
