QUESTION:
My 49-year-old husband has type 2 diabetes. He was diagnosed three years ago when his glucose was 845 mg/dL, with major weight loss, thirst and frequent urination. Glipizide 5 mg later kept his glucose near 126 mg/dL, but he stopped taking it in June. He has now lost weight and muscle and refuses to show me his readings or speak with his doctor. Could he already have kidney, heart or other damage? What should I watch for?
Quick Answer
Unexplained weight and muscle loss after stopping diabetes treatment may indicate severe hyperglycemia and insufficient effective insulin. With a previous glucose of 845 mg/dL, he has a history compatible with a life-threatening hyperglycemic crisis and should receive urgent medical assessment—today if the weight loss is continuing or symptoms are present. You cannot determine kidney, eye, nerve or heart damage by watching him at home; early complications often have no symptoms and require blood, urine, eye and foot examinations. Do not force him, restart glipizide without medical review, or hide medication in food.
Answer by Dr. Albana Greca, MD, MMedSc
Hello,
Your concern is justified. The priority is determining whether he has severe hyperglycemia, dehydration, infection or another cause of weight loss.
When glucose cannot enter cells effectively, the body may break down fat and muscle. High glucose also causes urination, thirst and dehydration.
Cancer, thyroid disease, infection, digestive illness or depression can also cause weight loss, so assessment must not focus only on diabetes.
A glucose of 845 mg/dL is compatible with hyperosmolar hyperglycemic state, or HHS, involving extreme glucose and dehydration. DKA or mixed DKA/HHS can also occur in type 2 diabetes.
Call emergency services now if he has:
Confusion, unusual sleepiness, fainting, inability to stand, repeated vomiting, abdominal pain, deep or difficult breathing, severe dehydration, new weakness on one side, chest pain, seizures, or a meter reading that says “HI.” Do not let him drive himself.
Ongoing weight loss, thirst, urination, blurred vision, weakness or high readings still require same-day urgent care even without pain.
Concealing glipizide in food is unsafe and unethical. It can cause severe hypoglycemia, especially with poor intake, weight loss, alcohol use, or kidney or liver impairment.
A capable adult may refuse treatment. Covert medication damages trust and can cause an emergency. If hyperglycemia is causing confusion, call emergency services for capacity and safety assessment.
Not without assessment. He may need glipizide, another medicine, combination therapy or insulin. Severe hyperglycemia with weight loss is a reason to consider insulin.
The clinician needs current glucose, HbA1c, kidney and liver function, eating pattern and his reason for stopping. See our glipizide safety guide.
No. Complications cannot be dated from months without medicine or excluded because he feels well. Risk depends on glucose, blood pressure, cholesterol and prior exposure.

Because his presentation was severe and weight loss has returned, the clinician may also reconsider diabetes type and insulin production.
Choose a calm moment and avoid blame: “I am worried because you are losing weight and muscle after stopping treatment.” Ask for one glucose check or urgent appointment and offer to attend.
Ask why he stopped—low glucose, side effects, cost, fear or depression may be involved. If he remains capable and refuses, do not treat him secretly. You may still tell his clinician what you observed.
This educational answer does not replace urgent assessment of weight loss or severe hyperglycemia.
