I have had diabetes for 16 months now and I seem to be tired for reasons unknown. I am 76 and except for the recent diabetes, I am healthy. No other medications. No allergies. Is it the metformin or the humolog or lantus that is having an effect on my energy level? Thanks for your answer.
Hello have gone through your question and understood your concern. Low energy can be a symptom of hypoglycemia and hypoglycemia can be a side effect of Humalog or Bantus. At the other side unusual tiredness, or weakness can be a symptom of lactic acidosis, a side effect of metformin. Other symptoms of lactic acidosis include abdominal or stomach discomfort, decreased appetite; diarrhea; fast or shallow breathing; a general feeling of discomfort; severe muscle pain or cramping. If you do not have any of these symptoms (apart low energy), Lactic acidosis can be excluded. I suggest checking your blood glucose several times every day(for some days)fasting, 2\u00a0hours after meals or random to see of you have hypoglycemia. In this case your insulines and your diabetes is the culprit of your low energy. If you do not have hypoglycemia and lactic acidosis, i suggest consulting your doctor for further investigations.(If the weakness persist)Hope I have answered to your questions. If you have other queries, feel free to ask.(you can ask me at Chat Doctor at my private link
