Sintomas ng Kidney Failure: Watch Out for These Warning Signs

Sintomas ng Kidney Failure: Watch Out for These Warning Signs

Kidney failure, also known as renal failure, can be described as the kidneys being unable to function well. Renal failure can be due to diseases that cause damage to the kidneys such as high blood pressure and diabetes. Kidneys also fail to function properly if they are blocked by kidney stones, blocked by scar tissue, or unable to receive enough blood to filter.

Sintomas ng kidney failure depends on the severity of the condition, what’s causing it and how fast the kidney is deteriorating. Kidney failure can either be acute or chronic.

Acute Kidney Failure

Acute Kidney failure refers to the sudden inability of the kidney to filter waste from the blood. It usually occurs within less than a few days and progresses rapidly.

People who have acute kidney failure are commonly those who are in the hospital or intensive care units who are suffering from other diseases such as heart disease, severe allergic reactions, organ failure, blood loss, and injury. It may also occur in people undergoing major surgery.

Sintomas ng Kidney Failure (Acute)

When the kidney deteriorates, toxins in the blood build up causing the person to feel weak. Anemia, a condition wherein not enough oxygen is carried throughout the body, can be a result of kidney diseases that cause kidney failure.


When toxins are accumulating due to kidney failure, it could interfere with a person’s cognitive function, particularly their ability to concentrate.

Irregular Heartbeat and High Blood pressure

When a person’s kidney is failing, the body attempts to increase blood supply to the kidneys. As a result, blood pressure increases.


Since the kidney is failing, extra fluid is not removed from the system which then results in swelling especially in the legs, ankles, feet (pedal edema), and around the eyes (periorbital edema).

Internal Bleeding

Since toxins in the blood are not eliminated, this can disrupt the microbiome in the gut which results in a compromised gut barrier.

When the gut barrier is compromised, it results in bleeding in the esophagus, stomach, and small intestines (Upper GI).

Chest Pain and Shortness of Breath

Since the excess fluid is not eliminated by the kidneys, fluid may build up in the lungs causing a tight sensation in the chest and difficulty breathing.

Chronic Kidney Failure

Chronic kidney failure, also known as chronic kidney disease (CKD), is described as the slow deterioration of the kidneys. This gradual loss of kidney function can slowly progress for months or years. Kidney damage brought on by CKD is often irreversible.

People who experience CKD are often those who have conditions in their immune system and urinary tract. Those who are using drugs and have prolonged exposure to medications such as ibuprofen might experience CKD.

People with chronic kidney failure may not experience symptoms during its early stages. Blood and urine tests are necessary to detect kidney failure during this stage. Symptoms of acute kidney failure are also found in people with CKD.

Sintomas ng Kidney Failure (Chronic)

Metal taste in the mouth and bad breath

When the kidney is unable to function properly, urea, a key component of urine, builds up. When this occurs, a person might taste food differently and will also have bad breath known as ammonia breath. The metallic taste in the mouth may also result in poor appetite.

Numbness and tingling

The build-up of toxins in the blood can cause damage to the nerves (uremic neuropathy). Numbness and tingling (paresthesia) may occur in the toes and feet.

Easy Bruising

People with kidney disease are usually the elderly. Their skin is less elastic due to aging and is worsened by uremia or the build-up of toxins in the body.

This results in the skin and blood vessels becoming frail causing the person to bruise easily. People with kidney disease may also experience dysfunction in platelets, a component in the blood that forms clots and stops bleeding.

Weak bones

When the kidneys are not functioning well, more parathyroid hormones are released into the blood. When this occurs, the body reacts by moving calcium from the bones and into the blood resulting in weaker bones. The Parathyroid hormone is responsible for regulating calcium levels in the blood.

Yellow-brown colored skin

Due to urea building up inside the body, the skin retains urochromes, the chemical responsible for the yellow color of urine. This results in the skin turning yellow.

If one or more of these symptoms start to manifest, make sure to seek medical attention immediately and ask your doctor for advice. Blood and urine tests are necessary to check if a person has kidney failure.

Key Takeaways

Kidney failure can either be chronic or acute. Symptoms of acute kidney failure include fatigue, confusion, irregular heartbeat, chest pain, and swelling. People who have chronic kidney disease will experience similar symptoms to that of acute kidney failure with the addition of other symptoms including a metallic taste in the mouth, yellowing of the skin, and easy bruising.

If you experience any of these symptoms, consult your doctor immediately.
