The Importance of Kidneys

Kidneys play a crucial role in our body by filtering blood and eliminating harmful substances. They also help maintain the balance of water and electrolytes. When kidney function declines or they become damaged, the effects can gradually manifest throughout the body.

Recognizing Symptoms of Kidney Issues

Experts indicate that certain symptoms may arise, particularly at night, when kidney health deteriorates. If these signs are not addressed promptly, the situation could worsen.

Frequent Urination

An increase in nighttime urination can signal a decline in kidney function. Healthy kidneys typically regulate urination, but when they are compromised, the frequency can increase significantly.

Swelling in Feet and Ankles

Damaged kidneys can disrupt sodium balance in the body, leading to fluid retention. This often results in swelling of the feet, ankles, and hands, which may be more noticeable during rest after a long day.

Skin Itching and Irritation

The kidneys are responsible for removing toxins from the body. If this process is hindered, waste can accumulate on the skin, causing itching and irritation, especially at night.

Insomnia and Fatigue

When kidneys fail, toxins can build up in the body, leading to insomnia. Individuals may experience frequent disturbances in sleep, restlessness, or even complete sleeplessness, along with persistent fatigue throughout the day.

Breathing Difficulties

Some individuals may experience difficulty breathing when lying down at night. This can be a serious symptom of kidney failure, as fluid may accumulate in the lungs. If you encounter this issue, seek medical advice immediately.
