Low Potassium Levels

Explore the Solution to Low Potassium Levels

Several individuals are unaware of the need for Potassium. It is the third most abundant mineral in the body, which plays a vital role in regulating fluid balance and sending the signals of nerve and muscle contractions. Potassium-rich food is beneficial for your health in many ways. These foods help to reduce blood pressure, protect against stroke and prevent kidney stones. It is said that 80% of Potassium is found in your muscle cells, and 20% of the nutrient can be found in the liver, bones, and red blood cells. It acts as an electrolyte inside your body.

Causes of Low Potassium

When the potassium level drops in your body, this condition is known as hypokalemia. There are many reasons for the low amount of this nutrient in the body. Some of the common causes of low potassium levels are 

  • diarrhoea 
  • kidney disease
  • vomiting
  • some diuretics 
  • excessive sweating
  • use of some antibiotics
  • Adrenal disorders
  • Low magnesium levels

Symptoms of Potassium Deficiency

There are many ways to determine if the potassium level drops in your body. By identifying some of the symptoms, you can determine whether the potassium level has dropped or not in your body


Since Potassium maintains the fluid balance in your body and retains water, constipation is the first sign of low potassium level. When Potassium decreases, your body cannot retain water, resulting in constipation.

2. Muscle Weakness

Potassium is necessary for muscle contractions and strengthens them. When you have a low amount of potassium in your body, your muscle power becomes weak. You may even suffer muscle cramps in your legs or arms due to the low potassium levels. It can also lead to paralysis of the muscle.

3. Fatigue

Since potassium plays a crucial role in regulating the function of cells and tissues when you have a low potassium level, your bodily function gets affected, which leads to low energy, therefore, you feel tired.

4. Problems in Breathing

To breathe correctly, you require some muscles, including the diaphragm. If potassium drops severely in your body, you will face serious breathing problems. You will have difficulty taking deep breaths, or may also experience shortness of breath.

5. Increase in Blood Pressure

Potassium helps to relax the blood vessels, which lowers blood pressure. A higher amount of sodium leads to high blood pressure. Since potassium balances the sodium levels in the body, your blood pressure will also be under control. If you have a tendency to have high blood pressure, you should lower your sodium intake and increase your Potassium intake.

Benefits of Adequate Level of Potassium

There are many benefits of this nutrient. Some of these benefits have been discussed below:

1. Regulates Fluid Balance

Our body consists of 60% water. 40% of the water is present in our cells, called intracellular fluid. The remaining portion of water is found outside of cells, including blood, spinal fluid, and between cells. The amount of water in our body is affected by potassium and sodium, which act as electrolytes. Potassium is our body’s primary electrolyte, which determines the amount of water inside the cells.

2. Regulates the Functioning of the Nervous System

The nervous system sends signals via synapses to the brain. These signals help regulate muscle contraction and control heartbeat and other body functions. These signals are formed with the help of nerve impulses. The presence of Potassium in the blood helps to generate nerve impulses. Therefore, an adequate level of this mineral in your body helps to maintain good nerve function.

3. Reduces Blood Pressure

An adequate level of this nutrient in the body helps to regulate sodium in the body. By increasing potassium intake, people with high blood pressure can keep their blood pressure under control. By consuming potassium food, you can also reduce the risk of stroke.

4. Prevents Kidney Stone

When calcium increases in urine, you are at risk of kidney stones. According to a study, potassium lowers the amount of urinary calcium excretion. Thus, you can prevent kidney stones with the help of high potassium intake. 

When Should You Visit a Doctor?

When any of the symptoms mentioned above is visible in your body and persists for a more extended time period, you should contact your doctor. For example, if you experience muscle paralysis, difficulty in breathing, or unusual heart rhythm, you should immediately visit your doctor and get your potassium level tested.

The first step to diagnosing low potassium is to test your blood sample, and the doctor will also examine your history or medications to determine the underlying low potassium factors. After determining the level, the doctor will also recommend you to go through a further blood test to check the level of electrolytes, including phosphorous, calcium, and magnesium.
