I have been reducing my sugar intake for the past six months. However, I somehow feel it is harder to concentrate. And in the morning, I feel pain in my abdomen and nausea that usually lasts until I take breakfast. Is there a reason why this is happening, Doctor? Does it sound like it should be something I should be worried about?

dr. Lee Keat Hong replied 1 year ago

Dear Sandyha, have you done any blood tests recently? It is worthwhile checking if your blood sugar level is normal since you have been reducing your sugar intake recently. If not do consider getting one done before deciding on the next course of action.

My stomach has been bloated since a few days ago. The gas makes me nauseous and I feel weak. If I press on the right side of my stomach, the pain is terrible. I also noticed a change in my toilet habits, as though I have constipation although it’s not painful. Does this condition need to be examined further?

dr. Lee Keat Hong replied 1 year ago

Dear Christopher, I do feel that you need further examination as your condition is making you feel weak and nauseous. Terrible pain at the right side of the stomach may be related to gallbladder and pancreas also. Do visit a nearby doctor for further history taking and physical examination before deciding on the next course of investigation (such as ultrasound of the abdomen).

Hi, Dr Lee. I saw you around mid 2018 cos i had v bad acid reflux and my tummy was very sensitive and bloated.You did colonscopy and found out that I had Hiatus hernia( lower Esophagus) and Non-erosive gastritis(Antrum). You initially prescribed Farmotidine, Omeprazole but somehow they didnt work on me.Eventually you prescribed Nexium and that worked( though initially i had v bad headaches).You also prescribed Domperidone to relieve my bloating. My problem is back and i wanted to see you again but discovered you are no longer at NUH. After i saw you in 2018, have been having regular checkups at sgh, cdld and was told if the same problem crops up ,take Librax and Farmotidine.So when the problem cropped up sometime in March i have been on these medications but i don't seem to be getting better.I honestly don't know if it was the covid vaccination that triggered this current bout cos after each does, i had diarrhoea, tummy cramps ( especially after the 2nd dose). Do you do virtual consult now? Would be very grateful for your advice.
