Hi,
Welcome to health care magic,
Dizziness or lightheadness while getting up or standing from a lying down position or a condition is known as syncope or a
presyncope.
It means it follows dizziness,lightheadnes and temporary semi consciousnesses for a while without actual becoming unconscious.
Here,I would like to ask you some questions regarding your medical history of
1) previous disease apart from
hypertension (for which you are taking these cardiac medications),
2) any recent or past surgery,
3) any past history of
head injury (like in accident)or
4) is there any other symptoms like
chest pain,palpitations,fatigue, blurring vision etc.
We will have to rule out causes of syncope from cardiac and non cardiac for which you will require detailed history, thoroughly clinical examination for heart like ECG,blood pressure measurements in different positions like supine,sitting and immediately after standing, echo cardiography of heart etc specially in persons who is above 60 years of age.
The underlying cause could be vasovagal,
orthostatic hypotension or postural
tachycardia or due to anxiety etc.
You will have to consult your physician first for thoroughly clinical assessment to detect the underlying cause.
Treatment will depend on the underlying cause.
Meanwhile you can do this things,
1) Maintain proper hydration and electrolyte balance by taking proper fluid intake throughout the day.
2) Positioning on the grounds immediately whenever there is
fainting spells and leg elevation, will cause pooling of blood in the upper part of body mainly in brain.
Hope i have explained it in a easy way to understand it.
Regards,
