Why do you feel lightheaded and dizzy?

Feeling lightheaded or dizzy is a condition that can affect any age, caused by many different medical conditions. Therefore, it is necessary to find out the reasons that cause these feelings in order to prevent and reduce them.

Many patients complain that they are dizzy, have a feeling that the room is spinning or have some difficulty with balance. Other patients may say they have a feeling of lightheadedness, such as when they faint or are about to faint. These symptoms have different meanings for each specific case. Lightheadedness and lightheadedness are not frequent causes of anxiety, but occasionally they are signs of an unusual medical condition of concern.

Some of the causes of lightheadedness and dizziness are:
Low blood sugar: Sugar is a form of energy for the body. Too little sugar in the blood stream, or hypoglycemia, is often associated with diabetes or its treatments. Hypoglycemia can also occur if the person is on an intermittent fasting diet or for some other reason. The person may feel weak and confused, and vision may be blurred. A few grams of sugar such as fruit juice, candy or glucose tablets are often used to restore blood sugar levels to the body quickly. If sugar is not provided in time, the patient will lose consciousness. Dizziness: This is not due to a fear of heights and dizziness is not actually a medical condition. Instead, dizziness is a symptom. Patients often feel dizzy when the patient's body or the surrounding space is spinning. The patient will feel weak, unbalanced or have problems with the stomach. The most common type of vertigo is peripheral vertigo, which occurs when a person has problems with the inner ear that affect balance.

Standing up too quickly: The medical name for this condition is orthostatic hypotension, also known as orthostatic hypotension. When the patient gets up from a sitting or lying position, the blood may not reach the brain in time, so the patient will feel lightheaded or dizzy. This feeling should go away after a few minutes, if it persists it can be a worse and more serious sign. Certain medications: Medications for high blood pressure, heart disease, and antidepressants can lower your blood pressure and make you feel tired and unable to think clearly. Insulin and a drug that lowers blood sugar in diabetics can work similarly and cause dizziness in patients. Lightheadedness can be a common condition if the patient is elderly or taking multiple medications. If you feel unsteady and unbalanced after taking any new medication, tell your doctor right away. Motion sickness: Traveling by train, car - car, plane or train can cause brain problems with the movement of limbs, walking of the patient. Some common symptoms may include vomiting or cold sweats. Occasionally, the feeling of seasickness after a cruise cruise can turn into seasickness on land. These disorders are called myasthenia gravis. This feeling of wobbling, swaying, or unsteadiness can last for several weeks or more. The researchers suggest that they may be to blame for the brain, not the inner ear. Dehydration: This can happen when the patient is not drinking enough water to replace the water lost through sweat or urine. So dehydration leads to low blood pressure and makes it difficult for the nervous system to control them. Patients often feel dry, tired and lightheaded. If the urine is yellow instead of clear, it is a sign that the person should drink more water. Meniere's syndrome or hearing disorder: This condition can cause a bout of vertigo that lasts from 20 minutes to several hours. Often times, the person will experience nausea and vomiting, the ears may feel tight and it is difficult to hear. In addition, tinnitus may also occur. The cause of this syndrome is currently not fully understood, but methods that can reduce the symptoms are taking medication, cutting salt or changing the diet and physical therapy.

Perilymph fistula: Trauma like a blow to the head can tear the tissue that separates the air-filled middle ear and the fluid-filled inner ear. This can cause dizziness and problems with balance. Patients may also experience tinnitus, ear strain, and sensitivity to loud noises. Changes in air pressure such as in an airplane or in an elevator can aggravate this condition. For treatment, the patient should take a few weeks to rest, if not, consider the option of surgery. Iron deficiency: The human body is provided with iron mainly from foods such as meat, tofu, spinach... to help red blood cells pump enough oxygen throughout the body. A deficiency of this mineral is called anemia. This makes the patient dizzy, weak, pale, and cold hands. Heavy menstrual bleeding is also a cause of anemia. Cardiovascular problems: Weakened heart muscle also known as heart failure, constricted blood vessels known as coronary artery disease, and similar heart problems can deprive oxygen-rich blood. This makes the patient dizzy, lightheaded to the point of fainting. These symptoms may begin without prior warning, occurring repeatedly over weeks. Therefore, when you have symptoms such as dizziness, chest pain, irregular heartbeat, fatigue... you need to notify your doctor immediately. Vestibular Neuritis: The vestibular nerve connects the inner ear to the brain. A viral infection can cause this nerve to swell suddenly. This will make the patient nervous, unsteady and have stomach problems. This symptom lasts from a few hours to a few days. However, it may take up to a month for a person to fully recover after that. When this condition affects hearing, it's called labyrinthitis, and it clears up on its own but requires proper rest. There can also be other causes: If a person suddenly experiences dizziness, it could be a sign of an emergency, such as a blood clot or rupture of a blood vessel in a stroke or aneurysm. If the patient has signs such as the arm, one side of the face is paralyzed, can't move, begins to talk, starts to talk, has a sudden headache... they should be taken to the emergency room right away.
