At 32 years of age with a body weight of 39 kg, being persistently underweight needs a proper medical and nutritional evaluation, not just medicines.
First – Rule out medical causes
Difficulty in gaining weight and rapid weight loss can be due to:
•
Thyroid disorders (hyperthyroidism)
• Poor appetite or malabsorption
• Chronic gastritis / IBS
• Anemia
•
Vitamin B12 /
Vitamin D deficiency
• Stress, anxiety, or irregular meals
• Worm infestation
I strongly advise basic tests:
• CBC
• Thyroid profile (T3, T4,
TSH)
• Vitamin B12 & Vitamin D
• Stool test (if digestion issues)
Diet & Nutrition (MOST IMPORTANT)
Weight gain happens only with calorie surplus + protein.
Daily tips:
• Eat small, frequent meals (every 2–3 hours)
• Never skip meals
• Add energy-dense foods:
• Milk, curd, paneer, cheese
• Nuts & seeds (almonds, peanuts, walnuts)
• Peanut butter
• Ghee or butter in meals
• Banana, mango, chikoo
• Protein is essential:
• Milk, curd, paneer
• Eggs / dal / soy / tofu
• Protein shake if needed
A personalized diet chart will help you gain weight safely. Consult on Practo for same.
Next Steps
Do light strength exercises (not cardio)
Adequate sleep (7–8 hours)
Manage stress
Health Tips
Weight gain of 2–3 kg in 1–2 months is realistic and healthy.
