6. Muscle Cramps and Twitching
Kidneys help regulate electrolyte levels, including calcium, potassium, and sodium. An imbalance in these can lead to:
- Painful muscle cramps
- Twitching or involuntary movements
- Weakness and spasms
If you experience regular cramps, especially at night, your kidneys could be struggling to maintain internal balance.
7. High Blood Pressure
Hypertension is both a cause and a consequence of kidney dysfunction. Damaged kidneys are less effective at regulating blood pressure, which creates a dangerous cycle. Watch for:
- Persistent blood pressure above 130/80 mmHg
- Headaches and dizziness
- Blurred vision
Unchecked, this can further impair kidney function and increase the risk of stroke or heart disease.
8. Metallic Taste in Mouth and Ammonia Breath
As waste builds up in the bloodstream—a condition known as uremia—it can affect your sense of taste and smell. Symptoms include:
- A metallic taste in the mouth
- Bad breath that smells like ammonia
- Loss of appetite
These are signs of toxicity building up in the body, and they warrant immediate medical attention.
