High Bloodsugar,hypertension, Pneumonia

Hi, My father ( 64) has been admitted to hospital, afetr being diagnosed with pneumonia and completing 2 sets of antibiotics ( Augmentin) with no effect. He has been on Hypertension medication for 19 years, and the doctor co-conculted with a specialist on his case file.

They found that his lung function is severy compromised, but also that he has elevated bloodsugar of 14. They seem to be very concerned as he has elevated blood pressure and fever. They are busy with pathology to identify the bacterial strain in the mucus specimen - but what I cannot understand is the link to the blood sugar levels. He has all the classic symptoms of ''pin and needles'' in his fingertips ( 3 weeks now), extreme thirst and night swetting. Could the bacterial infection cause or have lead to the blood sugar hype...? Very concerned... what treatment / food choices needs to be made now?

Hi Vi
Glucose in the blood comes from 2 sources. The first is what one eats and the second is from the liver. In diabetes the liver makes too much glucose and it is insulin that helps control it. When it comes to infections , then there are stress hormones like cortisol and adrenaline that tell the liver to make even more glucose, which is why the levels go up in the face of an infection. When a patient presents with high glucose readings during an infection, then it is either because they were an undiagnosed diabetic or pre-diabetic, or has what we call stress hyperglycemia(high glucose levels as a results of the infection, but settles back to normal when the infection has cleared). In terms of sorting out which one he has, time will tell, but sometimes if a test called an HbA1c is done at the time, then it can help, as it would normally be raised if he has undiagnosed diabetes for a while beforehand. If he is diabetic then he should see a dietician regarding food choices.

When you sick your blood sugar usually tend to be higher most probably because of the infection. If he is in hospital they most probably have him on a low G.I diabetic diet. Good luck I hope your father will have a speedy recovery. :-)
