Does radiation cause weight gain?

After completing my radiation therapy, I've noticed I'm steadily gaining weight. I'm confused because I thought it might have other effects. Does radiation cause weight gain?

I totally get it, dealing with body changes during therapy is incredibly stressful. Sometimes radiation doesn't directly cause weight gain, but the fatigue makes you less active, and certain other medications like steroids can add weight. Be gentle with yourself, your body is doing a lot of hard work right now.

While radiation itself doesn't typically cause weight gain, hormonal changes or fluid retention can sometimes happen. Try focusing on a clean, low-sodium vegetarian diet with lots of seasonal veggies and fruits to manage bloating. Always ask your clinical nutritionist before starting any strict diet plan during therapy.

Generally, radiation therapy is more likely to cause weight loss rather than gain because of fatigue and nausea. However, if you are receiving radiation for brain or prostate issues and are on steroids or hormone therapy, that's what actually drives the weight gain. Talk to your oncologist to pinpoint the exact reason.

If you notice sudden weight changes, it is better to get basic blood tests or thyroid panels done to find the cause. Try to plan these tests at a government-approved lab or use packages to save on costs. Don't waste money on fancy weight-gain or loss supplements, just stick to doctor's advice.

Sikai ki wajah se kabhi kabhi shareer me sujan aa jati hai jisse lagta hai wajan badh gaya hai. Isme chinta ki koi baat nahi hai, ilaj ke samay bas ghar ka seedha saadha khana khao. Doctor saheb se ek baar pooch lena, woh sab sahi bata denge.

Sometimes it is just fluid retention and not actual fat gain. Try to cut down on pickles, papad, and extra salt in your food to reduce the bloating. Just doing a light walk around the house or colony for 15 minutes can also help with blood circulation and managing weight.
