Dizziness is described as a feeling of faint or lightheadedness, but also feeling week and unsteady. Sometimes, it may involve a sense that the surrounding objects are spinning or moving. If this happens, the condition is called vertigo. Dizziness is not a medical condition itself but rather a symptom of some other condition. Sometimes, it occurs naturally as a result of certain disturbances in the body. This is a very common condition, and it accounts for many visits to the doctor’s office. If it repeats frequently, it may be a warning sign of potentially dangerous health conditions and demands medical attention. Most commonly, dizziness occurs upon rising, caused by the sudden drop in blood pressure.

Signs and symptoms of dizziness

As already mentioned, dizziness is separate from vertigo and lightheadedness. Knowing the signs and symptoms of dizziness may help to explain the symptoms to doctor and help narrow the list of possible causes. Often, people use the word “dizzy” to describe both of the feelings. When discussing the symptoms with doctor, it is important to be very clear and explain whether the lightheadedness or vertigo causes problems upon rising. Lightheadedness is a feeling that a person is just about to pass out. However, in this case, there is no feeling that the surroundings are moving. In vertigo, a patient has a feeling that the surroundings are moving, and a person feels like he or she is spinning, falling or whirling. In many cases, people may have problems with balancing, walking, or even standing.

Causes of dizziness upon rising

In most of the cases, the cause of dizziness upon rising is a drop in blood pressure. This sudden drop is actually a failure of autonomic nerve function that occurs when a patient suddenly changes body position. When a patient changes the body posture from lying to standing up, the sudden dip in the pressure occurs, and there is not enough of blood flow to the brain. Brain, deprived from oxygen, has difficulty functioning, and symptoms of dizziness occur.

Sometimes, this happens as a side effect of other underlying conditions, such as diabetes or Parkinson’s disease. These conditions affect the blood pressure and the heart rate, leading to the feelings of dizziness.

Dizziness upon rising can also occur as an effect of allergies, or more severe illnesses such as flu and cold. Whenever the body is compromised and sensitive, this autonomic nerve function may fail. Anything that causes dehydration can also cause dizziness upon rising.
