In 1940, Henry Woltman of the Mayo Clinic wrote about "headaches associated with decreased intracranial pressure". The full clinical manifestations of intracranial hypotension and CSF leaks were described in several publications reported between the 1960s and early 1990s. [ 94 ]
Early symptoms of hypovolemia include headache, fatigue, weakness, thirst, and dizziness. The more severe signs and symptoms are often associated with hypovolemic shock. These include oliguria , cyanosis , abdominal and chest pain, hypotension , tachycardia , cold hands and feet, and progressively altering mental status.
What causes vertigo and dizziness? “Dizziness is generally a more neurological cause or a potential cardiac cause. For example, it could be a blood flow issue or stenosis of a carotid artery ...
Hypovolemic shock is a form of shock caused by severe hypovolemia (insufficient blood volume or extracellular fluid in the body). [1] [2] It can be caused by severe dehydration or blood loss. [3] [2] Hypovolemic shock is a medical emergency; if left untreated, the insufficient blood flow can cause damage to organs, leading to multiple organ ...
The most common cause of hypovolemia is diarrhea or vomiting. The other causes are usually divided into renal and extrarenal causes. Renal causes include overuse of diuretics, or trauma or disease of the kidney. Extrarenal causes include bleeding, burns, and any causes of edema (e.g. congestive heart failure, liver failure).

Obstructive sleep apnea syndrome may cause morning headaches [54] Circulatory Hypoxia: Caused by insufficient perfusion of the affected tissues by blood which is adequately oxygenated. This may be generalised, due to cardiac failure or hypovolemia, or localised, due to infarction or localised injury.
Heavy-headedness is the feeling of faintness, dizziness, or feeling of floating, wooziness. [1] [2] [3] Individuals may feel as though their head is heavy; also feel as though the room is moving/spinning also known as vertigo. Some causes of heavy-headedness can be tough to get rid of and can last a long period of time, however most can be treated.
Vertigo typically indicates a problem in a part of the vestibular system. [2] Other causes of dizziness include presyncope, disequilibrium, and non-specific dizziness. [2] Benign paroxysmal positional vertigo is more likely in someone who gets repeated episodes of vertigo with movement and is otherwise normal between these episodes. [9]
