Dizziness and Drowsiness: The 10 Main Causes of “Dizziness”

Dizziness and dizziness can be caused by a variety of factors. Here are the possible reasons for dizziness and lightheadedness you may be feeling.

Many of us have asked ourselves the question, whether on ordinary days or in times of illness, “Why do I get dizzy?”

While dizziness can be uncomfortable, you probably won’t be surprised to learn that occasional dizziness is very common in adults. But you may not have guessed that dizziness is also very common, affecting almost 40% of people over the age of 40 at least once in their lives.

So how do you know if you have vertigo or ordinary vertigo? The main difference is that dizziness can cause nausea and vomiting, while dizziness simply throws you temporarily off balance. However, dizziness can vary in severity, ranging from just annoying to seriously worrying.

The following usually causes dizziness and lightheadedness. And what to do if you have one of these episodes.

1. Dizziness can be caused by an inner ear problem

One of the most surprising causes of vertigo is benign paroxysmal positional vertigo. Your inner ear contains calcium and protein-based sensory crystals called otoconia. As these crystals break loose and float around in the canals of your inner ear, you may experience a brief spinning sensation. It’s a simple mechanical problem that can and should be fixed with physical therapy, not medication or surgery.

Although this type of vertigo is the most common inner ear-related balance disorder, it only affects one in a thousand people each year. And while it can affect adults of all ages, this type of vertigo mostly affects older people. Most cases occur for no apparent reason. It has been linked to trauma, migraines, inner ear infections, diabetes and osteoporosis. After treatment, this problem can recur in 50% of patients within five years, especially if it is due to trauma.

2. Your ear’s balance system controls blood flow

Our balance system in the inner ear helps control our blood flow. The inner ear has the ability to know which way the tip is. When you transition from lying down to standing up, two structures in the inner ear, the utricle and saccule, sense gravity. They tell your cardiovascular system to direct blood flow to accommodate your change in position. If this process goes wrong, it can cause dizziness.

3. Low vitamin B12 can cause dizziness

A deficiency in this essential vitamin can lead to a number of neurological problems. Including a feeling of imbalance, low blood pressure and decreased blood flow to the brain. Vitamin B12 deficiency is easy to identify and treat, but it’s an often overlooked cause of dizziness.

Ask your doctor for a simple blood test to check your B12 levels if you feel dizzy. Good sources of vitamin B12 are meat, dairy products and products fortified with this vitamin.

4. Dizziness can be a symptom of heart disease

A simple cause of dizziness is sudden movements. For example, getting up from your seat or bed too suddenly. But sometimes dizziness is a sign of a heart problem. Cardiovascular causes of dizziness include leaky or narrowed heart valves, arrhythmias such as atrial fibrillation, and atherosclerosis. These diseases can cause dizziness because they reduce blood flow to the brain.

5. Migraines sometimes cause dizziness

It surprises some people to know that dizziness is often associated with migraines, with or without a headache. Other symptoms of migraine-related vertigo include sensitivity to movement, light, and sound. About 40% of people who suffer from migraines experience dizziness or light-headedness.

6. Dizziness can be associated with anxiety

Many people who suffer from dizziness, especially those in their 20s, can also be anxious. They usually don’t want to hear that dizziness is related to anxiety because it suggests it’s all in their head. But what’s in your head is your brain. And anxiety may reflect a disorder in brain function, which may be genetic in origin.

Compared to people without anxiety, people with anxiety disorders appear to sway more when exposed to a moving visual environment. And they sway in a way that seems synchronized with the visual movement. These people may be unusually sensitive to visual stimuli, as their dizziness may increase when looking at moving objects or walking in a large, bright store.

This is called visual addiction. Little is known about its frequency. It is likely that these disorders will be reclassified in the future based in part on genetics.

7. A boat ride or a water bed can cause dizziness

Dizziness on the first day after a cruise is not uncommon. For some people, this feeling, called seasickness, can last for months or even years. About 75% of sailors can experience such dizziness. Planes, cars, and trains can also cause dizziness. Relaxing on a water bed can also cause dizziness.

8. Dizziness and lightheadedness can be side effects of medication

So many drugs can cause dizziness that there are too many to list. However, high doses of blood pressure medications can cause dizziness. Especially in the elderly and those who have started taking a dose that is too high for them.

Check if the medicines you are taking may cause dizziness, drowsiness or problems with your balance by contacting your pharmacist or doctor. Careful review of drug lists and lowering the dose can sometimes yield surprising benefits.

9. Your diet or dehydration could make you dizzy

Even mild dehydration can cause dizziness or lightheadedness. Dehydration can also lead to low blood pressure. Which can cause dizziness. Diets can also cause dizziness as some of them lead to dehydration. Mild dehydration after losing just 1-2% of your body weight can cause dizziness.

10. There are several less common causes of vertigo and dizziness

Watch out for sedations. Because, along with other symptoms, they can indicate something more serious. Like warning signs of a stroke or a brain tumor.

A very rare disease associated with dizziness is Ménière’s disease. If you have persistent attacks of vertigo and hearing problems in one ear, it could be Meniere’s disease. This disease affects only about 0.2% of the population. It is sometimes found in adults between the ages of 40 and 60. Although it cannot be cured, it can be treated.
