Early Signs Of Low Potassium: Stay Informed For Optimal Health


Do you feel the numbness in your body from time to time? You might want to check your potassium levels in the body. Studies have concluded that the electrolyte imbalance may be a major cause of tingling sensation or numbness. And this electrolyte imbalance is a major setback when the body is not getting enough potassium in it. 

Medically speaking, your body is suffering from hypokalemia, which can affect your fluid balance, nerve function, and muscles. Failing to balance the potassium levels can be threatening, but the symptoms are very difficult to crack.

In this blog, we are going to understand the early signs of Low Potassium and give some tips to increase your electrolyte levels. We will also dive deep into healthy foods that are rich in potassium. So, if you are someone who is having digestive problems, or knows someone who is then this blog is for you.

Symptoms Of Low Potassium Or Hypokalemia

Potassium or Kalium is an essential nutrient that is responsible for many functions in your body. From maintaining the fluid balance to the transmission of nerve impulses, potassium plays a major role in it. Here are the symptoms of low potassium in your body that you might want to check from time to time.

Symptoms Of Low Potassium

1. Weakness Or Feelings Of Fatigue

Do you get bouts of weakness or fatigue randomly? Where your muscles just hurt out of the blue and you wish you could skip anything? These are the first signs of low potassium in your body. 

Potassium helps in contracting your muscles and produces insulin, so when you are feeling fatigued or have muscle pain, it is due to the potassium deficiency. Your muscles are not able to contract as usual and there is an underlying condition where there is a lack of glucose for you to be energetic. 

2. Bloating And Digestive Issues

Nowadays, not only the food but also the muscles that churn food are weak for digestion, Potassium is responsible for relaying the message from the brain to propel the food we intake, and when this function is skipped, there is slow contraction of muscles which results in slow movement of food. This slow movement often causes bloating or constipation which can disrupt the bowel movements

Eating a sufficient amount of potassium will help in the proper digestion of food and smooth passing out function. Although, constipation is a severe symptom that can be experienced when you are suffering from hypokalemia.

3. Tingling Sensations Over the Body

There are instances when your body or part of your feels tingles when there is a lack of movement for a longer period. But experiencing these tingling sensations occurs without a proper explanation, then it is worrisome.

Studies have shown that as potassium is a messenger from the brain, its lack of it can affect nerve function. If you get persistent tingling or numbness in your hands, feet, legs, or fingers then you should have it checked out.

4. Feelings Of Frequent Urination

Drinking sufficient water is necessary for the body, but going to the washroom every ten minutes can result in electrolyte imbalance. Potassium is a mineral that helps your kidneys to concentrate urine and balance the fluids in your body. Potassium deficiency can result in increased thirst with increased urination where your body throws out waste in the form of urine. It can also lead to damage in your kidneys, which requires medical help.

5. High Blood Pressure

With a spike in blood sugar levels, hypokalemia can also spike up the blood pressure in your body. As potassium helps your kidneys to absorb excess sodium and pass it in the form of urine, with low levels of potassium your body reabsorbs the existing sodium. And with excess sodium in your bloodstream, there is a chance of high blood pressure. Regular intake of potassium in your diet ensures electrolyte balance and gets rid of excess sodium from your body.

6. Difficulty In Breathing

In very rare cases, some findings suggest low levels of potassium can result in breathing difficulties. It helps to expand and contract the diaphragm properly. When there is a shortage of potassium in the body, you might come across finding it difficult to breathe.

This shortness of breath can be fatal when overlooked. There are also instances where high levels of potassium can also affect your lungs the same way.
