Kidney failure is a condition in which the kidneys stop functioning properly. The kidneys are two small organs that play a critical role in the body, filtering waste products from the blood and maintaining the balance of fluids and electrolytes.

When the kidneys fail, waste products build up in the blood, which can cause a range of symptoms and complications. In this article, we’ll take a look at some of the signs and symptoms of kidney failure that you shouldn’t ignore.

1. Fatigue and Weakness

One of the most common symptoms of kidney failure is fatigue and weakness. As the kidneys become less efficient at filtering waste products from the blood, the body may become increasingly fatigued and weak.

This can make it difficult to carry out everyday activities, and may also impact work and social life.

2. Swelling and Fluid Retention

Another common symptom of kidney failure is swelling and fluid retention. The kidneys play a key role in maintaining the balance of fluids and electrolytes in the body.

When they fail, fluid can accumulate in various parts of the body, leading to swelling in the legs, ankles, feet, and face. This fluid may also cause weight gain and a feeling of bloating.

3. Shortness of Breath

Shortness of breath is another common symptom of kidney failure. As excess fluid accumulates in the body, it can put pressure on the lungs, making it increasingly difficult to breathe.

This can be particularly problematic during physical activities, leading to shortness of breath and difficulty in performing even light exercise.

4. Nausea and Vomiting

Nausea and vomiting are common symptoms of kidney failure that are often overlooked. The accumulation of waste products in the blood can cause digestive problems, leading to nausea and vomiting.

People with kidney failure may also experience a loss of appetite, further exacerbating these symptoms.

5. Changes in Urine

Changes in urine are often an early sign of kidney failure. People with kidney failure may experience changes in the frequency, color, and volume of their urine. They may also have difficulty passing urine, or feel a burning sensation during urination.

In some cases, blood may also be present in the urine.

6. High Blood Pressure

Kidney failure can also cause high blood pressure. The kidneys play a crucial role in regulating blood pressure by controlling the balance of fluids and electrolytes in the body. When they fail, blood pressure may rise, leading to hypertension.

This can cause a range of symptoms, including headaches, dizziness, and shortness of breath.

7. Itchy Skin

Itchy skin is a less common symptom of kidney failure, but it can be a sign that waste products are building up in the blood. The kidneys play an important role in removing toxins and waste products from the body.

When they fail, these waste products can build up in the blood, causing itching and skin irritation.

8. Muscle Cramps

People with kidney failure may also experience muscle cramps, particularly in the legs and feet. These cramps may be caused by imbalances in electrolytes in the body, which can occur when the kidneys fail.

People with kidney failure may also experience muscle weakness and twitching.

9. Difficulty Concentrating

As the kidneys fail, the body may become overloaded with toxins and waste products. This can affect brain function, leading to difficulty concentrating and memory problems.

People with kidney failure may also experience confusion, irritability, and other mood changes.

10. Chest Pain

Chest pain is a less common symptom of kidney failure, but it can indicate a serious complication called pericarditis. This is an inflammation of the sac that surrounds the heart, which can cause chest pain, a fever, and difficulty breathing.

People with pericarditis may also experience a dry cough and fatigue.

If you’re experiencing any of these symptoms, it’s important to speak to your doctor. Early detection and treatment of kidney failure can help to prevent complications and improve outcomes.
