Circulatory problems if I lie or sit in bed for too long? – blood, vessels, heart, lungs

Hi there,

if I (f, 21) lie or sit too long in bed, after a while I have circulatory problems and then dizziness, weakness and circulatory problems throughout the day. Then I often have the feeling of tipping over. Even if I sleep too long, that’s how it is.

(Addition: as soon as I lie on my back while I have circulatory problems, I am very restless and nervous because I feel strange)

What kind of problem can that be?

Thank you very much:)
