Introduction:
Diabetes, as well as hypertension, cause significant deterioration in the quality of life as well as shortening the patient’s survival time. The aim of the study was to find answers to the following questions: 1) how many antihypertensive drugs are used by patients with hypertension and by patients with diabetes and hypertension; 2) are more antihypertensive drugs used by patients with impaired renal function; 3) are there any differences in the amount of antihypertensive drugs used between the observed groups.

Material and methods:
The study included 300 consecutive patients qualified for urgent admission to the Department of Internal Medicine, Diabetology and Nephrology in Zabrze. The reason for admission was unstable blood pressure in subjects with hypertension and diabetes or hypertension without diabetes. Body weight and height were measured using an AED mechanical column scale. 24-hour automatic blood pressure measurement was per-formed with an Oscar 2 device.

Results:
There were no statistically significant differences between the amount of medication used by patients with hypertension with or without diabetes. It was shown that along with deteriorating kidney function, the subjects used significantly more antihypertensive drugs (especially diabetic patients and those with hypertension).

Conclusions:
1. Patients with hypertension and with or without diabetes use on average 3.53 ± 2.22 antihypertensive drugs. In this regard, differences between the studied groups were not demonstrated. 2. Along with deteriorating kidney function, the number of antihypertensive drugs used by patients increases, especially in patients with diabetes. 3. Along with deteriorating kidney function, the amount of antihypertensive medication used is higher in patients with diabetes and hypertension compared to hypertensive patients without diabetes.
