5 morning signs that warn your kidneys are silently damaged

The kidneys are important organs that help filter waste, balance electrolytes, and produce hormones that regulate blood pressure and create red blood cells.

However, when kidney function begins to decline, the body can signal through very silent signs, especially in the morning. Recognizing these symptoms early can help detect and treat kidney damage promptly, before the disease progresses further.

According to experts from the Garnet Health hospital system in the US, there are 5 most common signs in the morning that can be related to kidney damage.

There are some morning signs that warn that the kidneys are silently damaged.

Swollen face in the morning

Swelling around the eyes or face right after waking up is a classic sign of kidney edema. When the kidneys are damaged, they can leak albumin into the urine, causing a decrease in the amount of protein in the blood, making it easier for fluid to leak out of the blood vessels and accumulate in the soft tissues. If swelling around the eyes is accompanied by foamy urine, rapid weight gain, or high blood pressure, kidney function should be checked, according to Garnet Health .

Foamy urine

Foamy urine that doesn't dissipate quickly can be a sign that your body is excreting too much protein, a condition called proteinuria. This is one of the earliest signs of damage to the glomeruli, the blood-filtering part of the kidneys. While some things like dehydration or frequent urination can cause temporary foaming, if it persists, your urine and kidney function should be tested.

Dry, itchy skin due to reduced kidney function

When kidney function is reduced, the body accumulates toxins and minerals such as phosphorus and parathyroid hormone, causing dry skin and severe itching, especially at night. Unlike normal dry skin, itching due to kidney disease is often bilateral and is not relieved by moisturizers. Persistent itching should be carefully evaluated with blood tests and kidney function.

Tired, poor concentration, forgetful

Brain fog can be caused by the kidneys not being able to remove toxins, anemia due to low erythropoietin (a hormone produced by the kidneys that plays a key role in making red blood cells), or sleep disorders. People often feel tired, sluggish, and have trouble concentrating. Testing your glomerular filtration rate (eGFR), hemoglobin, and other indicators can help determine the cause.

Ammonia breath

Breath that smells like urine or ammonia can be caused by high levels of urea in the blood - a clear sign of advanced kidney failure. If accompanied by nausea, fatigue and itching, the patient should be checked immediately, according to Garnet Health .

Thus, early stage kidney damage often does not cause obvious symptoms. However, if you carefully observe changes in the morning, from urine, skin, breathing to alertness level, you can recognize early warnings from your body. Early detection and timely intervention are the keys to protecting long-term kidney health.
