Brief Answer:
Your father needs evaluation.

Detailed Answer:
Hi, Mrs XXXXXXX

Thanks for your question.

I can understand your concern.

There may be following causes for polyuria (increases frequency of urination) in your father-
1) Uncontrolled blood sugar levels.
2) Urinary infections: Diabetes its self is a risk factor for urinary infections also with the age of 71, prostate problem is also another risk factor .

I would like to advise you to consult your doctor for detailed clinical examination along with it -
1) Check his blood sugar level (Fasting & Postprandial BSL and HbA1c) to confirm blood sugar control.
2) Following investigations may help in diagnosis after consultation with your doctor if blood sugar levels are fair
- Urine examination.
- Urine culture and sensitivity if pus cells present in urine.
- Complete blood count.
- Kidney function test (serum creatinine, urea, electrolytes, uric acid)
- Ultrasound of abdomen and pelvis for kidney size, shape, echo, prostate size, post void residue if any.

Depending upon clinical evaluation and test results appropriate diagnosis can be made without which appropriate medicines can not be suggested.

If UTI is confirmed there is need for antibiotics.
If blood sugar levels are not under control there may be addition of new antidiabetic medicines.


Hope I have answered your question.

Brief Answer:
It may be due to CKD.

Detailed Answer:
Hi Mrs. XXXXXXX

Thanks for your follow up question.

Raised serum creatinine in our father's case is most likely due to CKD (Chronic Kidney Disease).

CKD:
Long term diabetes and hypertension leads to Diabetic & Hypertensive retinopathy.
Which leads to CKD.
CKD is a progressive disease.
Progression of CKD depends on -
- Duration of Diabetes & Hypertension.
- Blood sugar level control.
- Blood Pressure control.
- Cholesteol control.
- Habits like smoking.
- Use of Nephrotoxic medicines.

By controlling above parameters one can prevent the development and progression in initial stages or slows the progression of of CKD.

Certain factors may lead to sudden deterioration of kidney function with base line CKD like-
1) Dehydration.
2) Infections.
3) Heart disease.
4) Use of nephrotoxic medicines like NSAIDs (Pain killers)

By reverting these factors we can bring down serum creatinine to base line level of CKD.

In your father's case the raised serum Creatinine levels may or may not become normal depending upon stage of CKD.
But we can try to prevent or at least slows the progression of CKD by-
- Controlling Blood sugar, Blood pressure & Cholesterol.
- Avoiding smoking.
- Avoiding use of Nephrotoxic Medicines.

He can use medicines like Nephrosave (which contain nutritional supplements, antioxidants) which decreases the toxic effects of different factors on kidney.
