Migraines and headaches are not one of the common symptoms associated with low potassium, or to use its official name hypokalaemia.

Potassium enters the body through foods such as fresh fruit and vegetables, fish, beef and juices such as orange and grapefruit. Excessive loss is the most common cause of low potassium rather than a low dietary intake, for example vomiting or diarrhoea.

The muscles in our body need a high level of potassium to function properly. The potassium in our bodies helps the neuromuscular cells to depolarize and repolarize, so when potassium is low the common symptoms are weakness in the muscles, muscle cramp and aches. It can also affect the heart leading to palpitations and in more serious cases it can even cause arrhythmias.

However as low potassium is usually the side effect of a more serious medical condition such as high blood pressure, dehydration or vomiting and diarrhoea, it is possible that another condition is causing migraines and headaches which has also led to low potassium.

If you think you may have low potassium, or are concerned about the cause of regular migraines and headaches it is advisable to visit your doctor for a full diagnosis and appropriate treatment. Less serious cases of hypokalaemia are either left for the body to recover on its own, or can be treated orally with potassium replacement tablets or by eating lots of potassium rich foods such as bananas and tomatoes. Only in the most serious cases, which are very rare, is low potassium treated intravenously.

I am a sufferer of Migraines. I also have a history of low Potassium. Years ago when experiencing a migraine, my young daughter brought me in a large glass of orange juice. I saw a marked difference in the headache. Since then when I experience a bad headache or migraine, I eat something high in Potassium.

The migraines are not caused by low potassium levels in blood. It symptoms includes nausea, cramps, constipation, palpitation, feeling thirsty, more urine, fainting, low blood pressure, depression and headache but not migraine.

Low potassium may not cause a migraine, but it can cause a headache which can in turn cause a migraine, so it can be a domino effect.

I think its not because Potassium is an element (and an electrolyte) that's essential for the body's growth and maintenance. It's necessary to keep a normal water balance between the cells and body fluids. Potassium also plays an essential role in the response of nerves to stimulation and in the contraction of muscles. For low potassium, what you need is Potassium Citrate which involved in cardiovascular health, energy production and more and on herbal vitamins and supplements has that to offer.
