Hypotension
Hypotension is low blood pressure; normal individual variation should be separated from dehydration, medications, bleeding and endocrine causes.
Hypotension means low blood pressure. In some people it is normal and causes no complaints, but weakness, fainting, dizziness, cold sweat or worsening when standing require looking for a cause.
Blood pressure may fall because of dehydration, salt loss, bleeding, infections, medications, heart problems, endocrine disorders or prolonged under-eating. Symptoms matter as much as numbers.
Keto And Pressure
During the first weeks of keto, water and sodium are lost, so pressure may fall more than usual. Dizziness on standing is often related to low salt, low fluid or an overly abrupt calorie deficit.
What To Track
Blood pressure and pulse lying and standing, salt, water, coffee, medications and symptom timing are useful. If blood pressure drugs are used, weight loss may change dose needs.
When Help Is Needed
Fainting, chest pain, shortness of breath, black stool, bleeding, high fever or sudden severe weakness require medical evaluation. This should not be explained only as “low pressure from keto”.
When Low Pressure Is Dangerous
In a trained person, low blood pressure without symptoms may be normal. But fainting, falls, confusion, cold skin, dehydration, blood loss or sudden weakness change the situation: the cause must be found, not just covered with coffee.
