It might be normal to feel a little dizzy when finishing up a grueling workout or maybe from standing up too quickly, but if you're getting wobbly throughout the day, it could indicate a more serious issue.

Dizziness can make you feel lightheaded, woozy, and unstable. It can happen when there's an issue with sensory organs (the eyes and ears in particular) and, in extreme cases, can even lead to fainting, nausea, and vomiting. It's a symptom of many disorders, making the list of potential dizziness causes pretty long.

Having an occasional bout of dizziness is fairly common, but if you notice chronic episodes or your dizziness lasts for a substantial length of time, it's a good idea to talk to your healthcare provider.

Here are some of the causes of dizziness to be mindful of.

Inner Ear Problems

Vertigo affects balance and coordination and is commonly caused by a problem with the inner ear. Vertigo causes a spinning sensation, making it feel much like motion sickness or as if you're tilted to one side.

The most common cause of vertigo is an inner-ear problem called benign paroxysmal positional vertigo (BPPV), according to a 2014 article in Primary Care: Clinics in Office Practice.

As MedlinePlus explains, the inner ear has very sensitive tubes filled with fluid and, when you move, the fluid in these tubes moves. This helps your brain keep track of your body's position. But, if small calcium crystals (called canaliths) break free and float around in these tubes, your brain gets mixed signals. This causes you to feel like your spinning or that everything around you is spinning.

One thing an ear, nose, and throat specialist can try to help you with vertigo is a simple repositioning exercise called the Epley maneuver. This series of head movements is used to move the crystals out of your inner-ear tubes to stop the symptoms.

Meniere's disease (MD) is another common inner ear disorder that causes attacks of vertigo, fluctuating hearing loss, tinnitus (ringing in the ears), and a feeling of fullness in the ear. It is thought to be related to excess fluid buildup in the ear (National Institute on Deafness and Other Communication Disorders).

Medications, dietary and behavioral changes, physical therapy, hearing aids, and surgery are used to treat Meniere's disease.

Migraines can be another severely disabling cause of dizziness. Symptoms also include intense head pain, nausea, vomiting, and fatigue. If you suffer from migraines, it's helpful to know some common warning signs, so you can prepare for or try to prevent one. Your healthcare provider will also find it helpful if you keep track of your symptoms as to when they occur, what they feel like, and how long they last.

Blood Pressure Drops

"When you get up too quickly from a sitting or lying position and your blood doesn't travel as quickly up to your head, you will experience a 'head rush' feeling," Sherry Ross, MD, OB-GYN and women's health specialist at Providence Saint John's Health Center in Santa Monica, Calif., told Health. "Medically, this is known as orthostatic hypotension, where there is drastic drop in blood pressure when you stand up."

You might also notice feeling faint or confused, or experience blurry vision, added Dr. Ross—but it's usually nothing to worry about. However, if it happens often, consider speaking with your medical practitioner, advised Dr. Ross. "It's always best to follow up with your healthcare provider if you experience this symptom more frequently with time or it's associated with fainting."

Poor Circulation

Poor blood circulation to your brain can cause dizziness, as well as weakness, numbness, and tingling. This is because your brain isn't receiving as much blood as it needs.

Underlying heart conditions could be the reason why your brain isn't getting enough blood. Or, in rare cases, dizziness could be a symptom of a so-called "mini stroke" or transient ischemic attack (TIA), in which blood flow to the brain is temporarily blocked. Other symptoms of TIA include weakness on one side of the face or body, blurred vision, trouble speaking, and coordination problems, according to MedlinePlus.

Though symptoms only last a few minutes, they can indicate risk of a future stroke. If you experience an attack of dizziness accompanied by any other symptoms of TIA, you'll want to contact your healthcare provider to determine the cause.

Neurological Conditions

Certain neurological conditions, like Parkinson's and multiple sclerosis (MS), can be a cause of dizziness.

Parkinson's disease affects the motor system and involves shaking of the hands, arms, legs, jaw, and face, according to MedlinePlus. Dizzy spells can happen in those with Parkinson's as a result of low blood pressure, either due to the disease itself or medication used to treat it, according to the Parkinson's Foundation.

MS is characterized by sensations like numbness, tingling, and weakness. Dizziness or episodes of vertigo can occur in those with MS, making them feel off balance with bouts of lightheadedness and spinning sensations.

Dizziness can be a side effect of some medications. As a December 2013 article published in the Journal of Pharmacology and Pharmacotherapeutics reported, the list of medications that may cause dizziness is rather long:

  • Antibiotics (for treating bacterial infections)
  • Diuretics (for helping your body get rid of salt and water)
  • Anti-hypertensive drugs (for lowering blood pressure)
  • Mucolytics (for thinning mucus)
  • Anti-inflammatory drugs (for reducing inflammation or swelling)
  • Anti-depressants (for treating depression)
  • Cholesterol-lowering medicines
  • Anti-fungals (for killing or inactivating fungi)
  • Anti-malarials (for treating malaria)
  • Heavy metals (like arsenic, mercury, and cis-platinum)
  • Anti-psychotics (for managing various psychotic disorders)
  • Parkinsonian drugs

Talk to your prescribing healthcare provider about the medications you're taking if you are experiencing dizziness. Your healthcare provider may be able to adjust your dosage or suggest an alternate treatment that won't produce that side effect.

Low Blood Sugar

Low blood sugar (hypoglycemia) occurs when the body doesn't get enough sugar (or glucose). When you're blood sugar is low, you can feel shaky, dizzy, anxious or weak, and hangry. Low blood sugar can also lead to confusion and difficulty speaking, according to MedlinePlus.

If your dizzy spell is related to low blood sugar, grab a snack. Carbohydrates can help bring your blood sugar back up. If this type of dizziness happens often, you'll want to discuss it with your healthcare provider.

Getting enough iron is essential, especially for women, according to the Office on Women's Health. Iron helps you produce red blood cells and maintain a healthy immune system. Eating iron-rich foods can help reduce your risk of an iron deficiency.

When your body is parched, lightheadedness and dizziness can be tied to low blood pressure. If you are dehydrated, you may also be feeling thirsty, urinating and sweating less, feeling tired, having dry skin, and noticing dark-colored urine.

Underlying health conditions (diabetes or high blood pressure, for example) can cause dehydration. So it's important to discuss any symptoms like dizziness with your healthcare provider as soon as you notice them. Otherwise, don't stress about drinking eight glasses of water a day; instead, drink when you're thirsty and try adding more water-rich fruits and veggies (like cucumbers and melons) to your diet to boost hydration.

Anxiety Disorders

Think anxiety makes you dizzy? You're not alone: Anxiety can cause not only dizziness, but other physical symptoms like a pounding heartbeat, unexplained aches and pains, and shortness of breath, according to MedlinePlus.

Avoiding triggers for your anxiety, like caffeine and certain medicines, can prevent this type of dizziness. But some triggers aren't as easy to avoid. In the throes of a panic or anxiety attack, try to focus on slowing your breathing or using a calming mantra. Taking quick, shallow breaths will only worsen lightheadedness or dizziness.

Heat exposure can lead to dizzy spells and lightheadedness if you're not hydrated or prepared for extreme temperatures.

Heat-related illness can also make you feel nauseated and confused, according to MedlinePlus. Heatstroke occurs when the body's core temperature reaches 106 degrees Fahrenheit, and it is considered a medical emergency.

Keep hydrated, stay cool, and limit your time in the heat to avoid heatstroke. If you notice someone experiencing symptoms of heat-related illness, help that person out of the sun. And if the symptoms are severe, get that person medical care as soon as possible.

Motion Sickness

Motion sickness is a dizziness that occurs when you are traveling in by car, train, airplane, and boat, according to MedlinePlus. Before getting dizzy from motion sickness, you may feel queasy and have cold sweats.

Basically, your brain is getting mixed messages. Your eyes and ears are telling your body that you are moving, while your arms and legs are telling you that you are sitting still. Some medications, like Dramamine, can help, as can sitting where you'll have a smoother ride and looking out into the distance.

Food Allergies

When your body's immune system reacts to certain proteins in a food, an allergic reaction occurs. Reactions can vary from mild to severe, even life-threatening, symptoms (FDA - Food Allergies).

Common food allergens include nuts, milk, eggs, soy products, and shellfish. Allergic reactions, and the resulting drop in blood pressure, can cause dizziness.

Try to avoid your trigger foods whenever possible by being especially cautious when dining out. Your doctor may recommend Benadryl (diphenhydramine) or prescribe steroids or other treatments to help mitigate dizziness and other symptoms.

When To Seek Help

If your dizziness comes with persistent headache or vomiting, neck pain, a fever, blurred vision, difficulty hearing and speaking, numbness in the limbs, loss of consciousness, chest pain, or droopiness among facial features, call your healthcare provider immediately.

These dizzy spell causes aren't normal—there's something more serious going on. You will want to get checked by a medical professional to figure out where your dizziness is coming from and how to stop it.
