Causes of Lightheadedness

Do you know what can cause lightheadedness? People keep asking about the causes of lightheadedness after exercise and causes of lightheadedness when standing up. Why these particular situations? And what are the real causes? Read on to know.

Here are the three primary causes of lightheadedness 

1. Positional change

The most basic cause of lightheadedness occurs in the moments you quickly move from a seated/lying down position to a standing position. As you stand on your feet, the blood flow rushes down, leading to less blood flow to the top region of your body i.e., the brain. 

The phenomenon can lead to a decrease in blood pressure which may make you feel like you are going to pass out.

If it happens, try to sit back or lie down, so that the blood starts flowing towards your brain.

2. Dehydration

Dehydration triggers the same aspect of blood pressure we just talked about. When you are sick, overheated and are not consuming a significant amount of fluids, the volume of your body lowers down. Thus, lowering the blood pressure which may cause you to faint. The problem with less blood pressure is that your brain doesn’t get enough blood flow and thus, oxygen and glucose, which are transported through the blood, doesn’t reach the brain enough.

If you suddenly feel faint, the best option is to quickly drink a couple of glasses of water. However, severe dehydration will require intravenous injections of fluid in the blood.

3. Heart attack and stroke

Heart attack or stroke talks about the possibility of some blockage in the arteries. It is a sign that your heart isn’t pumping blood like it usually should. This means your brain doesn’t get enough blood flow like in other cases. Thus, leading to less oxygen and glucose and more chances of passing out.

Since heart attacks and strokes are more common in elders due to their advancing age, elders must take special care.

Lightheadedness is one of the most common symptoms in the elderly, which implies the danger of heart attacks and stroke. It must be taken care of to ensure the elder stays away from them.

However, heart attacks and stroke are emergencies, and one must always stay ready for them. These are what causes severe lightheadedness. Download the Emoha app on your elder’s phone, which gives the ability to notify the family and experts at Emoha whenever the elder is in an emergency. 

Apart from these, the other common causes of lightheadedness in elders are

  • Low blood sugar
  • Use of alcohol, tobacco, or illegal drugs
  • Allergies
  • Some medications
  • Cold and flu
  • Sickness because of heights
  • Fever
  • Vomiting 
  • Diarrhoea
  • Hyperventilation (very deep or fast breathing)

Lightheadedness Treatment – Get Rid of Lightheadedness

So, how to overcome lightheadedness? The simplest way is to increase the blood flow to your brain. This can be done by lying down, drinking more water, drinking sugary fluids, or getting injections of fluids that are passed to your bloodstream through your veins.

Drinking fluids which have electrolytes is also seen to be quite effective. 

If these tricks don’t work, then you can go for the following treatment methods. Doctors use these when the condition is severe.  

  • Medications for anxiety
  • Medications for nausea
  • Medications for migraine
  • Water pills
  • A low-salt diet
  • Balance therapy which includes vestibular rehabilitation (these are exercises which help make your body’s balance system stronger and less sensitive to sudden motion)

Sometimes it is a problem with the inner ear that causes balance problems. Doctors suggest getting antibiotic injections in the problematic inner ear.

They may also recommend getting a removal done of the sense organ that is a part of the inner ear. The process is called labyrinthectomy. With the sense organ removed, the function of that inner ear is disabled.


The best way to prevent lightheadedness is to keep drinking enough water regularly. Especially if you are sick. Also, avoid getting overheated in the sun.

Stay clear from illegal drugs, alcohol and tobacco as they are one of the significant causes of lightheadedness. Avoid medications that may result in lowering your blood pressure. Also, never discontinue or take medications without consulting a doctor who knows your medical history.

Lightheadedness is not a serious condition but can degrade the quality of your life. For the elderly, it may cause bouts of fainting. This is not good at all, because elders may have other diseases which may get worse because of fainting and lightheadedness.

For example, you don’t want your diabetic elder to faint in the bathroom one day. Diabetics need to take their medicines on time and eat healthy food every 2 to 3 hours. If the elder is alone in the house and faints, it will be pretty problematic.

That’s why it is suggested to have a caregiver with your elder at all times, especially during the day if not night. The caregiver not only provides the elder with the physical support they need but also emotional support. 

You can also download the Emoha app. The elder can take advantage of the numerous features we have on the app. These include the emergency button feature which allows the elder to notify us and the family members if they need any help suddenly,
