test came back ok . They gave zantax for acid reflux . Can ulcer cause weight loss
Hi there!
Aside dietary intake, weight gain/ loss also depends on physical activity, BMR, height, weight, hormonal/ endocrine status, GI causes such as malabsorption, medication side effect etc. Constipation is unlikely to be a factor in lack of weight gain. I would suggest waiting for a few more weeks before considering a review with his treating doctor, if the weight is below the normal range of BMI.
Hope this is helpful.
Take care!
