on March 11, 2019

When you’re pregnant, you experience radical hormonal changes. These hormonal changes are often the cause of numerous illnesses, diseases and conditions commonly experienced while being pregnant. To counteract this, it is important to have a diet that is specifically designed to balance out these changes. One nutrient that is considered important for this purpose is potassium. In this article, we will discuss the importance of potassium during pregnancy and other important things related to it. Read on to find out an entire guide on potassium during pregnancy:

What is Potassium?

An essential mineral that the body requires, potassium is responsible for numerous important body functions. It helps maintain a balance of electrolytes and fluids inside the body while also being responsible for sending signals and impulses from your nerves to your muscles to help them contract.

Role of Potassium During Pregnancy

When you are pregnant, your body expands and will need extra minerals to counteract the side-effects of pregnancy.

  1. Fluid retention is a common problem in pregnancy. Consuming potassium helps alleviate this issue.
  2. It is common that women have an electrolyte imbalance during pregnancy. This can cause your immune system to become weaker. Potassium combats against this.
  3. Leg cramping and restless leg are common during pregnancy and could be caused due to a mineral imbalance. Potassium along with calcium and magnesium is important to avoid this.

Ideal Daily Intake of Potassium

It is extremely important to note that potassium shouldn’t be consumed in large doses. A potassium overdose in your body can be just as dangerous as having low potassium levels. When consuming supplements or foods rich in potassium, consult a doctor to understand what your natural potassium levels are and the quantity of the supplement you should consume. A general guideline for daily intake of potassium is 4,700 milligrams if you’re not breastfeeding and 5,100 milligrams if you are.

What is The Normal Range Of Potassium During Pregnancy?

The normal range of potassium during pregnancy depends on how far along you are. For instance, during the first trimester, the normal range is between 3.6 mmol/L to 5 mmol/L, during the second trimester the normal range is between 3.3 mmol/L to 5 mmol/L and during the third trimester you can expect a normal range between 3.3 mmol/L to 5.1 mmol/L. Doctors consider a range of 4.4 mmol/L a safe range to maintain during the entire span of the pregnancy.

High Potassium (Hyperkalaemia) in Pregnancy

High potassium levels are extremely dangerous during pregnancy; it can cause a strain of a condition known as hyperkalaemia and in some cases, which can lead to kidney failure or cardiac arrest. It can also cause severe and near-fatal dehydration and aggravate a type of type 1 diabetes of the mellitus strain.

What Are its Causes

There can be numerous reasons why you get hyperkalaemia. Some of these are:

  1. Overdose of certain drugs
  2. Overdose of supplements
  3. Eating too much potassium rich foods

Signs And Symptoms

It is important that you identify hyperkalaemia as soon as possible and seek medical attention for this. Here are some signs and symptoms of this condition to help you identify it.

  1. Irregular heartbeats
  2. Extreme fatigue
  3. Chest pains
  4. Irregular pulmonary functions that lead to trouble breathing
  5. Numbness
  6. A tingling feeling

For more signs and symptoms of this condition please consult your doctor.

Effects Of High Potassium During Pregnancy

The effects of high potassium during pregnancy can be dangerous. It can lead to miscarriagespremature delivery or in some cases a fatal outcome for both the mother and child.

Treatment

Early diagnosis is essential to treating this condition. If diagnosed early you will be

  1. Given calcium supplements to prevent damage to heart muscles
  2. Administered insulin, certain diuretics or sodium polystyrene sulfonate to lower potassium levels
  3. Severe cases may call for dialysis if there is kidney failure.

It is usually considered a medical emergency and should be treated in a hospital environment with 24-hour care surrounding the mother.

Low Potassium (Hypokalemia) While Pregnant

Another strain of hypokalaemia is the one where your potassium levels are far too low. This can be equally dangerous for the body and should be treated with care. A potassium deficiency can also lead to muscle cramps, trouble with the delivery and other unwanted outcomes for your pregnancy.

Causes

Here are a few causes for low potassium during pregnancy:

  1. An imbalanced diet
  2. Constant vomiting leading to mineral imbalances in the body
  3. Diarrhoea leading to a mineral imbalance in the body
  4. Fluid retention

Signs of Potassium Deficiency

It is important to identify and treat a potassium deficiency during pregnancy. Here are some low potassium in pregnancy symptoms.

  1. Muscle cramps
  2. Weakness or tiredness
  3. Heavy constipation
  4. Dizziness or lightheadedness
  5. Depression
  6. Irregular heartbeat or rhythm
  7. A tingling feeling
  8. Numbness
  9. Extremely dry skin
  10. Low blood pressure

Effects of Low Potassium During Pregnancy

The effects of low potassium are commonly considered dangerous. However, a high potassium level is considered much worse and can lead to fatal outcomes. In extremely rare cases where the potassium is extremely low, it could, in theory, lead to cardiac diseases but this is highly unlikely. It is more common to face a condition known as Edema which is irregular swelling and inflammation throughout your body during pregnancy or you can get a form of UTI due to water retention. This is also a cause of premature delivery. If you think you have these symptoms see a doctor immediately.

Treatment

Treating low potassium during pregnancy can be extremely easy. Here are a few ways to ensure you bring your potassium levels up:

  1. Eat a well-balanced diet with potassium-rich food like potatoes and avocados
  2. Take the recommended dose of potassium supplements
  3. In extreme cases, your doctor may restore potassium levels through the use of intravenous administration of electrolytes

Potassium Supplements

At this point, ‘the question can you take potassium pills while pregnant’ must have crossed your mind. The answer is yes; you can take supplements but stick to recommended doses that your doctor prescribes and run it by him before you start. It is considered safe to eat potassium-rich food, however, as the chances of an overdose are less likely.

Safe Potassium-Rich Foods for Pregnant Women

Here are a few foods that are naturally rich in potassium that are safe for pregnant women.

A renowned super food, avocados are magnificent for pregnant women because they are a balanced source of vitamins and minerals important for your body, including potassium. Eating one avocado a day is considered extremely healthy.

A fruit that is often considered a staple in most parts of the world, not only does the banana help combat constipation by being a natural laxative; it also is rich in fibre and potassium. One banana a day is all you need to keep your potassium levels balanced.

Tips

Here are a few tips to keep in mind when adding potassium to your diet.

  1. Never take supplements without talking to a doctor. An imbalance in potassium levels can be extremely dangerous.
  2. Don’t exceed recommended dosages of supplements.
