Low Blood Pressure (Hypotension): Causes, Symptoms, Treatment and Home Remedies

Low Blood Pressure (Hypotension): Causes, Symptoms, Treatment and Home Remedies

By RealMedVision  |  Updated March 2026  |  7 min read

Most people have heard about high blood pressure. But low blood pressure — also called hypotension — can cause just as many problems if it is left unnoticed or ignored.

The good news is that in most cases, low BP is manageable. Knowing what it is, what causes it, and what actually helps can make a big difference.

Quick fact: Normal blood pressure is around 120/80 mmHg. When it drops to 90/60 mmHg or below, that is considered low blood pressure.

When BP is too low, your heart, brain, and other organs do not get enough blood. That is when symptoms like dizziness, weakness, and fainting start to appear.

What Causes Low Blood Pressure?

Low BP does not just happen randomly. There is usually a reason behind it. Some of the most common ones are:

  • Not drinking enough water — dehydration is actually the most common cause, especially in summer or after vomiting and loose motions
  • Low hemoglobin (anemia) — when blood does not carry enough oxygen, BP can drop
  • Heart problems — a weak heart muscle or irregular heartbeat can reduce blood flow
  • Standing for too long — blood starts pooling in the legs, which reduces flow to the brain
  • Certain medicines — BP tablets, water pills, or antidepressants sometimes cause BP to fall too much
  • Nutritional deficiencies — low iron, Vitamin B12, or folate can all contribute
  • Pregnancy — it is common for BP to drop slightly in the first few months
  • Hormonal issues — thyroid or adrenal gland problems can also be a cause
Important: Without knowing the actual cause, treatment will not work properly. If low BP keeps happening, get it checked by a doctor.

Symptoms You Should Know

The body gives clear signals when blood pressure is too low. Here is what to look out for:

  • Dizziness or feeling lightheaded — especially when you stand up quickly
  • Fainting or nearly fainting
  • Unusual tiredness or body weakness
  • Blurry or hazy vision
  • Feeling nauseous or like you might vomit
  • Trouble focusing or feeling mentally foggy
  • Fast or shallow breathing in more serious cases

If these symptoms keep repeating, do not brush them off. They are your body asking for attention.

Medical Treatment — What Doctors Usually Prescribe

Please note: Never take medicines for low BP on your own. A doctor will check your BP readings and run tests before deciding what you need. The wrong medicine can actually make things worse.

Depending on what is causing the low BP, a doctor may suggest one of the following:

FludrocortisoneHelps the body hold onto more salt and water, which raises blood volume. Usually given for long-term low BP cases.
MidodrineTightens the blood vessels slightly to push BP up. Commonly used when people feel dizzy every time they stand up (postural hypotension).
Iron TabletsPrescribed when the low BP is caused by anemia. The doctor will usually confirm this with a blood test first.
Vitamin B12 SupplementsGiven when weakness and low BP are linked to a B12 deficiency. More common in older patients.

Home Remedies That Actually Help

For mild low BP, you do not always need medicine. These simple habits can make a real difference:

Drink more water
8 to 10 glasses a day is a good target. Dehydration is one of the easiest causes to fix. Coconut water is also helpful, just do not overdo it.
A little more salt (with doctor's advice)
Slightly increasing salt in your diet can help raise BP. Salted buttermilk or a light salty soup works well. But do not do this without asking your doctor first.
Eat smaller meals more often
Eating one large meal can sometimes cause BP to dip. Smaller, more frequent meals throughout the day help keep it steady.
Get up slowly
If you stand up too fast after sitting or lying down, BP drops suddenly and you get dizzy. Take a moment before rising — it sounds simple but it really works.
Tea or coffee occasionally
Caffeine can give a temporary boost to BP. It is fine as occasional relief but should not become your main treatment.

What to Eat When You Have Low BP

Food will not fix low BP overnight, but the right diet helps your body deal with the root cause — whether that is anemia, dehydration, or nutritional gaps.

  • Pomegranate and apples — great for overall blood health
  • Spinach and beetroot — rich in iron and folate, which help with anemia
  • Eggs and milk — good sources of Vitamin B12 and protein
  • Dates and raisins — give quick energy and some iron when you feel weak
  • Yogurt and buttermilk — help with hydration and digestion

The goal is not to chase a magic food. It is about eating consistently well so your body has what it needs.

When Low BP Becomes an Emergency

Most of the time, low BP is manageable at home. But there are situations where you need to go to a hospital right away — no waiting, no home remedies.

Go to the hospital immediately if:
  • BP keeps falling below 90/60 mmHg and you feel dizzy or weak
  • You faint or collapse suddenly
  • You feel chest pain or pressure
  • Your speech becomes unclear or you feel confused
  • BP dropped after an accident or significant blood loss
These signs mean your vital organs may not be getting enough blood. Do not wait.

Two Real Patient Stories

Story 1: A 35-year-old woman felt dizzy every morning when she got out of bed. After a check-up, her doctor found both low BP and low hemoglobin. She was given iron tablets and advice on diet. Within a month, the dizziness was mostly gone.
Story 2: An elderly man felt very weak and kept getting dizzy. Tests showed it was simply dehydration causing the BP drop. His doctor told him to drink more water, take ORS, and manage his salt intake. A few days later his BP was back to normal — no heavy medicines needed.

Frequently Asked Questions

What BP reading is considered low?

A reading of 90/60 mmHg or below. Normal is around 120/80 mmHg.

Can I treat low BP at home?

Mild cases often respond well to more water, better diet, and simple lifestyle adjustments. But if symptoms keep returning or are severe, see a doctor.

What foods help raise low blood pressure?

Iron-rich foods like spinach and beetroot, protein sources like eggs and milk, and hydrating options like buttermilk and yogurt are all helpful.

When is low BP a medical emergency?

When it is accompanied by fainting, chest pain, slurred speech, mental confusion, or follows an injury or blood loss — go to the hospital right away.

To Sum It Up

Low blood pressure is not something to panic about in most cases. For many people, drinking enough water, eating well, and making small daily habit changes is all it takes.

But if your BP keeps dropping, symptoms are getting worse, or you are fainting — that is your body telling you it needs proper medical care. Do not ignore it.

The right treatment at the right time is always the best path forward.
