What causes numb feet and blurry vision in a woman with T1D?

This Premium Q&A, reviewed and published, features a real conversation between an iCliniq user and a physician.

Patient's Query

Hello doctor,

I am a 45-year-old female struggling with type 1 diabetes and hypertension. I have been using an insulin pump for three years to manage my diabetes, but my doctor recently suggested that continuous glucose monitoring might be beneficial for me. My latest lab reports show a microalbuminuria level of 35 mg for 24 hours, which has raised concerns about potential kidney complications. Currently, I am using insulin, with a total daily dose of 38 units. My blood pressure fluctuates between 145/92 and 138/88, and I take Lisinopril 10 mg daily to manage it.

Additionally, I have started experiencing occasional blurry vision and numbness in my feet, which is causing me some worry. Could you explain what these symptoms might indicate and provide insights on the preventive measures I should consider?

Kindly help.

Hi,

Welcome to icliniq.com.

I read your query and understand your concern.

From what you’ve described, your symptoms may be related to elevated blood sugar levels, which can lead to complications affecting the nerves, eyes, and kidneys. It's important to maintain good control of both blood sugar and blood pressure to prevent further progression.

Using a continuous glucose monitor (CGM) could be very helpful. CGMs offer real-time tracking of glucose trends and can improve your ability to manage diabetes and adjust insulin dosing more precisely.

Your microalbuminuria result indicates early kidney involvement, and keeping your blood pressure consistently below 130/80 mmHg is key. Lisinopril is a good option, but your doctor may consider adjusting the dose or switching to other medications such as Telmisartan or Amlodipine if needed. Reducing salt intake can also help lower your blood pressure.

Be sure to keep up with routine blood work like complete blood count (CBC), liver function tests (LFT), renal function tests (RFT), vitamin D, and B12, and schedule regular eye exams and foot checks. These are important for catching any early complications.

In addition, staying active, avoiding tobacco, and eating a balanced, low-sodium diet will

support better control of both conditions.

I hope this information helps. If you have any further queries, kindly do not hesitate to ask.

Thank you.
