Dizziness when lying down can be caused by benign paroxysmal positional vertigo, ear infections, or poisoning. These conditions usually subside without treatment, but persistent dizziness may require medical attention. Severe symptoms should be reported to a doctor immediately.
The most common causes of dizziness when lying down are benign paroxysmal positional vertigo, ear infection, and some forms of poisoning. These conditions are usually temporary and often subside without treatment. Other illnesses, such as nausea or food poisoning, can occasionally cause dizziness that may persist even if the patient is lying down.
Vertigo is a feeling that often causes nausea, a “dizzy-headed” sensation, or a spinning sensation in the room. It is one of the most common medical ailments because so many factors can cause dizziness. Most of the time, lying down or sitting with your head between your knees helps relieve symptoms associated with dizziness, but occasionally they may persist despite changes in position.
Benign paroxysmal positional vertigo can cause dizziness when lying down and is a condition that occurs more often in the elderly. It’s not known exactly what causes it, but it’s likely due to debris inside the ear that builds up over time. This condition usually goes away on its own and doesn’t last more than a few months. Patients may receive medications to relieve symptoms in the meantime.
Ear infections can cause dizziness in much the same way as paroxysmal positional vertigo. When the inner ear is thrown out of balance by buildup, infection, or other material, the balance of the body can be thrown off and dizziness and nausea can occur. Most infections clear up on their own, but bacterial infections may require antibiotics.
Sometimes, conditions like food poisoning or stomach viruses can cause dizziness when lying down. Although lying in bed usually causes dizziness to decrease, a very serious illness can cause it to persist. Treatment will depend on the condition. Long-lasting or very severe dizziness should be further investigated by a doctor. If poisoning is suspected, contact a poison control center or emergency services immediately.
Dizziness accompanied by severe nausea or vomiting, shortness of breath, or other symptoms can be a sign of a serious medical condition. A doctor should be notified if dizziness is sudden and does not subside within several hours. Those who are severely light-headed should not drive and should be taken to the doctor by a friend or an ambulance if necessary.
