Though you might think something as ordinary as feeling winded after taking the stairs is normal, Dr Katherine Pohlgeers previously told HuffPost that if your breathing “stay[s] elevated past three minutes or a prolonged period of time, that’s when it becomes more concerning”.

But what about feeling dizzy when you stand up?

We asked Dr Donald Grant, a GP and senior clinical advisor at The Independent Pharmacy, what it could mean and when to see a doctor.

“Feeling dizzy when you stand up can be normal, and it usually occurs due to blood pressure changes, which means the brain gets less blood flow for a brief moment,” Dr Grant explained.

“This is particularly common after standing or sitting for extended periods, but outside of that, several potential causes shouldn’t be ignored.”

One of the most “common” of these, he added, is “postural hypotension” (also known as orthostatic hypotension), or a sudden lowering of blood pressure that happens when you go from sitting to standing.

“Other common signs of this include blurred vision, general weakness, confusion and nausea,” he explained.

The NHS said it’s important to see a doctor if you get repeated signs of low blood pressure, like dizziness and fainting.

“Dizziness may also be caused by dehydration, so it’s important to drink enough fluids each day, especially as we approach the warmer months,” Dr Grant continued.

“While it can vary depending on age, health conditions and the weather, people should generally aim to drink six to eight cups of fluid each day.”

Additionally, some medications and pre-existing health conditions, like anaemia, diabetes, and heart problems, can make you feel dizzy when you stand up too.

“If dizziness occurs regularly or suddenly worsens, seek urgent medical attention. A qualified health professional can provide more tailored advice on potential causes and treatment,” shared Dr Grant.

In general, the NHS suggests you should see a doctor if your dizziness or vertigo keeps coming back or lasts a long time, or if hearing or speaking becomes difficult.

You should also visit your doctor if you experience tinnitus (ringing in the ears); double or blurred vision; numbness or weakness in the face, arms or legs; changes in pulse; fainting; headaches or nausea, according to the health service.
