###Human: What can be the reason for my frequent hunger and weight loss? ###Assistant: Hi. Based on your query and attached reports (attachments removed to protect patient identity) my opinion is as follows:  Based on your reports, there is no abnormality. No signs of any lymphoma or leukemia. Weight loss of 2 kg over 3 months is normal. Dehydration can cause up to 1-2 kg weight loss within a week and 2 kg should not be worrisome. Thyroid profile is good and there is no anemia. Regular moderate activity, protein-rich diet, good hydration (5-6 liters of water per day) should be helpful. Night sweats are usually a sign of cancer. However, the weight loss will be in the range of more than 10% within 2-3 months and additionally, for lymphoma, multiple groups of lymph nodes would be enlarged or in case of leukemia WBC (white blood cell), the differential would show a high number of blasts or immature cells. None of which are found. Additionally, there are no frequent new infections, indicating good bone marrow and immune function. There is no presence of any cancer of blood-forming cells. 1. Regular moderate activity. 2. Have good protein rich diet. 3. Keep yourself hydrated. Drink at least 5-6 liters of water per day.
