Dizziness on Standing May Have Causes Beyond Low Blood Pressure
Feeling dizzy when you stand up can happen for many reasons.
Sometimes blood pressure briefly falls because blood moves toward your legs.
Not drinking enough water, being sick, or losing fluids can also cause dizziness.
Low blood levels, low blood sugar, and some heart problems may be responsible.
A spinning feeling can point to an inner-ear problem.
Dizziness can also sometimes be connected to a problem in the brain.
Fainting, chest pain, trouble breathing, severe headache, weakness, or speech problems are warning signs.
If dizziness happens often or is severe, a doctor should check the cause.
Dizziness after standing can result from orthostatic hypotension, but it may have several other causes.
Dehydration from inadequate fluids, sweating, fever, vomiting or diarrhoea can reduce blood volume.
Anaemia, nutritional deficiencies and low blood sugar may also trigger dizziness and related symptoms.
Heart rhythm disorders, valve problems, inner-ear conditions and neurological issues can require medical attention.
Fainting, chest pain, severe breathlessness, sudden headache or neurological changes require immediate care.
