As a 17-year-old girl who is 182 cm tall and weighs 53 kg, why am I unable to gain weight despite using a mass gainer protein powder for four months, and what can I do?including going to the gym?to safely put on weight when I have an underactive thyroid (for which I take Thyronorm 25) and a genetic condition that makes me naturally tall and thin (Marfan syndrome)?
It is wonderful that you are proactively looking after your health. Having Marfan syndrome means your body naturally has a fast metabolism, and it is crucial to be very careful with exercise. Before starting any gym routine or lifting weights, please consult your cardiologist, as Marfan syndrome requires gentle, joint-safe activities to protect your heart. Additionally, ask your doctor to check your thyroid levels to ensure your Thyronorm 25 (levothyroxine) dose is perfectly balanced. Working with a registered dietitian can help you build a safe, high-calorie meal plan tailored to your unique body. You are doing great, and taking these cautious steps will support your health beautifully.
