Feeling Lightheaded? Here are 10 Reasons Which Might Be Causing Those Dizzy Spells 

Many of us have wondered, on routine days or during illness, "Why am I dizzy?"

While dizzy spells are unpleasant, it should come as no surprise that adults experience dizziness on a regular basis. Even while it's not typically brought on by anything life-threatening, you still need to exercise caution. Dizzy episodes can have a variety of causes, including emergencies like strokes or ear conditions involving crystals (yes, really). Aside from being uncomfortable, dizzy episodes can drastically disrupt your life by making you hesitant to do particular things or concerned that you may be really ill.

Here are ten potential causes of light-headedness.

1. Dehydration

Even slight dehydration could be causing you to feel dizzy or light-headed. Some people are simply prone to feeling lightheaded or fainting when they get hot and sweaty and lose too much fluid. It's typical in a hot environment, like as standing in church during the summer.

When you don't drink enough fluids, your blood volume decreases, lowering your blood pressure and preventing your brain from receiving enough blood, resulting in lightheadedness. A glass of water may be enough to make you feel better, but if you haven't eaten or drunk much in days, your body will want more to rehydrate. You might require a fluid intravenous infusion. A doctor can determine whether you require electrolytes such as potassium or salt.


2. Stroke and heart attack

Lightheadedness can be an indication of a heart attack or stroke in its most severe form. Lightheadedness is frequently accompanied by other symptoms of a heart attack, such as chest discomfort, shortness of breath, nausea, arm pain, back pain, or jaw pain. Symptoms of a stroke include a rapid onset of headache, numbness, weakness, vision abnormalities, difficulty walking, or slurred speech. However, in older persons, lightheadedness may be the only sign of a heart attack or stroke, particularly if it persists. In that scenario, every second counts, so rush to an emergency room as soon as possible.


3. Nutritional deficits

Eating a variety of meals is a smart approach to meeting your nutritional needs, but occasionally you can still find yourself lacking in certain vitamins and minerals. Particular iron deficiencies, which can induce iron-deficiency anemia, which entails not having enough healthy red blood cells, can cause symptoms of dizziness. However, other vitamin deficiencies, such as a deficiency in folate, vitamin B12, or vitamin D, may also be at fault.

Increase your intake of fortified foods, seafood, nuts, and dark leafy green vegetables to be sure vitamin deficiencies aren't the source of your lightheadedness.


4. Respiratory issues

People with various respiratory conditions or those who are suffering from respiratory failure may experience dizziness because their bodies are not getting enough oxygen. Hyperventilation, which is frequently linked to several psychological illnesses, may, however, be the only cause in some circumstances.

To identify dizziness caused by a respiratory condition, blood work, oxygen saturation testing, and pulmonary function tests are frequently utilized. Due to its impact on lung function and the balancing system in our minds, Post Covid-19 Syndrome (also known as Long Covid or Long Haulers) has now been added to the list of illnesses that can make us feel lightheaded.


5. Depression, anxiety, and stress

In reality, depression and anxiety have significant physical effects on how our body functions, despite the common misconception that they are only psychological problems. Fast onset of symptoms (such as a panic attack), extended, untreated anxiety and depression, or excessive exposure to stress (from work, family, finances, or health) can all cause abnormal nervous system activity, which can result in a variety of dizzy symptoms.

Since both patients and medical professionals can discount this as a valid cause of dizziness, these factors are frequently disregarded. However, receiving the right care might help you manage and perhaps get rid of your symptoms.


6. Low blood sugar

If you've ever skipped a meal, you know what it's like to be extremely hungry. That's because eating insufficiently can adversely affect your blood sugar levels. If your blood sugar drops too low, your brain won't obtain the fuel—glucose—that it requires for energy, and you may experience lightheadedness.

Usually, eating something will make your symptoms go away. Lightheadedness should be treated seriously if you have diabetes and take medicine to lower your blood sugar since it may be an indication that your blood sugar is dangerously low, which can cause seizures and unconsciousness.


7. Anxiety

Many persons who suffer dizziness, particularly those in their twenties, may also experience anxiety. Persons with anxiety problems appear to sway more when exposed to a moving visual environment than people without anxiety disorders do. They also appear to move in time with the visual movement as they sway. Because their dizziness can worsen when they observe moving items or are in a big, bright store, these persons may be especially sensitive to visual stimulation. This is known as a visual dependency, and nothing is known about how widespread it is.


8. Medications

Many different medications could be the cause of this, but to name a few: Dizziness is a known side effect of anti-seizure medications, antidepressants, and sedatives. If blood pressure-lowering drugs work a little too well and your blood pressure falls too low, you might also feel lightheaded.

When in doubt, schedule a visit with your doctor to go over your drug regimen and see whether anything could be to blame for your dizziness. Don't forget to note any supplements you take. Even if you believe a specific drug to be the problem, don't stop taking it without first consulting your doctor.


9. Getting up too quickly

A condition known as orthostatic hypotension, which describes a sharp drop in blood pressure upon standing, is what causes you to feel dizzy or even see black spots in your vision when you get up abruptly from a seated position. It normally doesn't cause much concern, but if it occurs frequently or if it worsens rather than improves after a few minutes, it may be worth mentioning to your doctor.


10. Vestibular dysfunction

This is one of the most common causes of dizziness.

Your inner ear organ and the neurological connections that connect it to your brain make up your vestibular system. You can detect head motion and position thanks to it. Numerous complaints of dizziness can be the result of issues with this system. An inner ear infection can harm the vestibular nerve and, in addition to the early symptoms of ear discomfort, hearing loss, and vertigo can occasionally lead to long-term problems with vertigo.
