My father aged 70 had his pacemaker replacement operation on 7.7.21. Prior to this his blood report revealed high blood sugar with hbA1c of 15 and thereafter he has been treated with insulin and Geminor. During his stay in the hospital and after discharge on the 10th July 2021, he is suffering from constipation. From 11th onwards, after two hours of taking his antibiotics in the morning, he starts vomitting. Past couple of days, we gave ondem so he didn't vomit. But today again he vomitted. He always had regular bowels and therefore is in discomfort. We gave him isabgol but it didn't help. He has lost enormous amount of weight in past few months and is anemic too. Kindly advice, what should we do?
