Medication Side Effects: Impact on Kidney and Uric Acid Levels - Cardiology

Understanding the side effects of medications, particularly those related to kidney function and uric acid levels, is crucial for managing health effectively. In your case, you have been taking antihypertensive medications since July of last year, and while your initial blood tests showed normal kidney function and uric acid levels, recent tests indicate a decline in kidney function and a significant increase in uric acid levels from 6 to over 9.

The medication you mentioned, which contains a diuretic (泌排特錠), can indeed have side effects that may impact kidney function and uric acid levels. Diuretics are commonly prescribed to help control blood pressure by promoting the excretion of sodium and water through urine. While they are effective for managing hypertension, they can also lead to dehydration and electrolyte imbalances, which may adversely affect kidney function, especially in individuals with pre-existing kidney issues.

Increased uric acid levels, or hyperuricemia, can occur as a side effect of diuretics. This happens because diuretics can reduce the kidney's ability to excrete uric acid, leading to its accumulation in the blood. Elevated uric acid levels can result in gout, a form of arthritis characterized by sudden and severe pain, redness, and swelling in the joints. Therefore, it is plausible that the diuretic component of your antihypertensive regimen is contributing to the rise in your uric acid levels.

Moreover, the changes in your kidney function indicators (blood glucose levels and other markers) could also be influenced by the medications you are taking. Some antihypertensive drugs, particularly those that are diuretics, can lead to changes in kidney function over time, especially if they are not closely monitored. It is essential to have regular follow-ups with your healthcare provider to assess kidney function and make necessary adjustments to your medication regimen.

Given your situation, it is advisable to consult with your healthcare provider about the following steps:
1. Medication Review: Discuss the possibility of adjusting your current antihypertensive medications. Your doctor may consider switching to a different class of antihypertensive that has a lesser impact on uric acid levels and kidney function.

2. Monitoring: Regular monitoring of kidney function and uric acid levels is crucial. This will help in identifying any adverse effects of the medications early on.

3. Lifestyle Modifications: In addition to medication adjustments, lifestyle changes such as maintaining a healthy diet, staying hydrated, and engaging in regular physical activity can help manage blood pressure and uric acid levels.

4. Specialist Referral: If your kidney function continues to decline or if uric acid levels remain elevated, your doctor may refer you to a nephrologist (kidney specialist) for further evaluation and management.

In summary, while your current medication regimen may be contributing to the changes in your kidney function and uric acid levels, it is essential to work closely with your healthcare provider to address these issues. Regular monitoring, potential medication adjustments, and lifestyle changes can help mitigate the risks associated with your treatment and improve your overall health.
