Dizzy and lightheaded when I stand up
You get up from a chair or out of bed. The room tips. Your head feels light, and your sight may go grey or narrow for a few seconds.
Some people have to sit right back down and wait. Others feel sick, sweaty, or hear a ringing sound. It usually passes in under a minute once you sit or lie down.
Doctors call this orthostatic hypotension. It means your blood pressure drops when you stand. In diabetes, damaged nerves are a common reason for that drop.
When to see someone
Call 911 or your local emergency number if you have chest pain or trouble breathing. Do the same for a racing or pounding heart that will not slow down.
Call 911 for slurred speech, a droopy face, or weakness on one side. Do the same for a sudden bad headache or double vision. These can be a stroke.
Go to the emergency room if you faint and you cannot explain why. Go too if you hit your head, or if you take a blood thinner and you fell.
Call your doctor the same day for black or tarry stools, or blood in your vomit. These point to bleeding. Call the same day if you cannot keep fluids down.
Call the same day if the dizzy feeling stays while you sit or lie still. That is not a standing problem, and it needs a look.
Book a visit within a week if it happens most days. Do the same if it started after a new pill or a dose change. Also book if you have come close to fainting, or if you are falling.
Ask for a lying and standing blood pressure check. The nurse takes it after you lie down, then again one and three minutes after you stand. It is quick and it can show the problem right away.
Why it happens
When you stand, gravity pulls about a pint of blood into your legs and belly. Nerves are supposed to notice this at once. They tell your blood vessels to squeeze and your heart to beat faster.
Years of high blood sugar can hurt those nerves. This is called autonomic neuropathy. The signal then comes late or comes weak, so your brain gets less blood for a few seconds.
Other things stack on top. Being low on fluid means less blood to move.
Some pills lower blood pressure even more. Heat, alcohol, and big meals can all make it worse.
What else it could be
Not every dizzy spell on standing comes from nerve damage. The cause changes what helps, so it is worth sorting out.
Low fluid. Your mouth is dry, your pee is dark, and you feel it most on hot days or after a stomach bug. It gets better within hours of drinking.
Medicine. The spells started after a new pill or a higher dose.
Water pills, blood pressure pills, prostate pills, and some drugs for depression are common ones. It is often worst an hour or two after the dose.
Low blood sugar. You feel shaky, sweaty, hungry, or muddled.
Food fixes it in about fifteen minutes. This can hit while you sit still, not only when you stand.
Inner ear (BPPV). The room truly spins, like a ride. It comes when you roll over in bed, look up, or bend down, not just when you rise.
It stops in under a minute and your blood pressure is fine.
Low iron or blood loss. You feel tired all day, look pale, and get short of breath on stairs. Black or tarry stools or heavy periods are clues.
Heart trouble. You feel a pounding, racing, or skipping heartbeat.
You faint with no warning at all, or you get dizzy while sitting or during exercise. This one needs a doctor, not home care.
Simple faint. After pain, fear, a hot shower, or long standing in line, you feel sick and sweaty first. This kind is common and usually not from diabetes.
How to read the grades below
The options below come from our page on Diabetic Neuropathy. Each one carries two labels.
The first label is the evidence grade. A means strong trials in people, B means smaller or mixed studies, and C means early or limited findings. D means lab work only, and “insufficient” means the research cannot settle it yet.
The second label is the traditional tier. T3 means long use in more than one tradition, T2 means long use in one, and T1 means known use. T0 means no such record.
These grades come from research on Diabetic Neuropathy, the parent Health Topic, not on dizzy and lightheaded when i stand up.
A grade tells you how strong the research is, not how well something will work for you. Talk to a doctor or pharmacist before you start anything, above all if you take other medicines.
What to try first
Stand up in two steps. Sit on the edge of the bed first. Count slowly to thirty, then rise.
Prime your legs before you rise. Pump your feet up and down ten times. Squeeze your thigh and seat muscles as you stand, and keep squeezing for a few seconds.
If you feel it start, act fast. Sit or crouch down right away. Cross your legs and squeeze, or grip one hand in the other and pull hard.
Drinking water through the day is one simple option. A large glass of water twenty minutes before you get up can help. Extra salt helps some people, but ask your doctor first if you have heart, kidney, or blood pressure problems.
Bring every pill bottle to your next visit. Ask if any of them drop your blood pressure. Do not stop or change a dose on your own.
Ask about knee-high compression socks. Some people also raise the head of the bed four to six inches on blocks. Skip long hot showers and big heavy meals if those set you off.
Now the graded options. None of them lift your blood pressure when you stand. They aim at nerve health and blood sugar, which is the root problem for many people here.
Exercise has an evidence grade of A and a traditional tier of T3. Start seated or lying down, such as a bike you lean back in. Yoga also has an evidence grade of A and a traditional tier of T3, but skip fast stand-ups and head-down poses until your spells settle.
Alpha Lipoic Acid has an evidence grade of A and a traditional tier of T0. Curcumin and Vitamin D also carry an evidence grade of A with a traditional tier of T0. Ask for a blood test before you take vitamin D.
Berberine has an evidence grade of A and a traditional tier of T0. It works on blood sugar, so it can push your sugar too low next to diabetes drugs. Your doctor needs to know if you take it.
Benfotiamine has an evidence grade of B and a traditional tier of T0. It is a form of vitamin B1. Capsaicin (topical) has an evidence grade of A and a traditional tier of T0, but it is a skin cream for foot pain and does nothing for dizziness.
Chamomile has an evidence grade of B and a traditional tier of T3. Evening Primrose Oil has an evidence grade of C and a traditional tier of T1, which means the proof is thin. Evening primrose can thin the blood a little, so tell your doctor if you take blood thinners.
Three options have an evidence grade of insufficient. Palmitoylethanolamide (PEA) sits at traditional tier T0. Acupuncture and Colocynthis both sit at traditional tier T3, which means long folk use rather than trial proof.
How long it takes
The two-step stand and the leg squeeze work the same day. Try them for a week and see.
More water and compression socks often help within a few days. A salt change, if your doctor says yes, may take one to two weeks.
If a pill is the cause, a dose change can help in a few days. Your doctor will guide that.
The graded options aim at nerve health, and that is slow. Most studies of them run eight to twelve weeks. Nerve repair takes months, and some nerve damage does not come back.
Keep a simple log. Write down each spell, the time, and what you were doing. Bring it to your visit, since it tells your doctor more than memory does.
