Can insulin resistance cause rapid weight gain?

Question

Hello doctor,

My dad is 65 and has had type 1 diabetes for decades. Over the past year, he has gained about 30 pounds, which seems odd since his appetite has not really changed. His blood sugar levels are consistently high, and his HbA1c was 10.5% the last time it was checked. Recently, he has been complaining about his hands shaking and feeling weak, especially in the mornings. Could this weight gain be related to a metabolic shift in his body, or could it be something entirely different, like Parkinson’s or another neurological issue?

Please advise.

Hello,

Welcome to icliniq.com.

I understand your concerns. Please do not worry; I am here to help you.

The weight gain in your dad could be due to insulin resistance (a condition that occurs when cells in the body do not respond properly to insulin, a hormone that regulates blood sugar) or complications like fatty liver disease, which are common in individuals with diabetes. Morning weakness and hand tremors may also result from severe glucose fluctuations or hypoglycemia, rather than Parkinson’s disease. However, a neurological issue cannot be ruled out without further evaluation, and these symptoms should not be ignored. It is important to plan for tests such as thyroid function, liver enzymes, and nerve health assessments (for signs of neuropathy). An endocrinologist can review his current diabetes management plan and make adjustments to improve blood sugar control, which may help alleviate some of these symptoms.

If neurological symptoms persist or worsen, it would be prudent to consider a consultation with a neurologist to rule out conditions like Parkinson’s disease or other potential neurological disorders. Early intervention, especially with neurological conditions, can help manage both metabolic and neurological issues more effectively, leading to better long-term outcomes.

I hope this helps you.

Thank you.
