Hi doctor,

My father has had diabetes for the past 15 years. He is frequently urinating in the night and also struggle to get sleep. He exercises in the morning, eats well, and is physically fit, but occasionally drinks alcohol, recently it has become frequent. Is it due to this? Would his blood sugar level be increased? Also, he takes the tablet Metformin 500 mg twice daily. Should the dose be increased? Should he check his blood sugar again or does he have any other health issues? Please help.



Welcome to

Thank you for your query. There are four reasons for frequent urination. Increase in blood sugar levels, Urinary tract infection, Kidney dysfunctions and Medicines which increase urine are the reasons. Yes, he should check his blood sugar levels before breakfast in fasting state and two hours after having meal. I suggest you to get Hemoglobin A1 C levels done, if it is not done in last six months, Fasting lipid profile done if not done in last one year, urinalysis, and urea, creatinine, electrolytes levels done, if not done in last one year. Also continue the same tablet Metformin. Follow up here after the report of hemoglobin A1c and alternate day monitoring of fasting and random blood sugar for one week. Thank you.
