I recently spoke to a sports doctor who told me how he had fainted at work due to low blood pressure. He said he didn’t drink enough water, had a long day and was dehydrated.
He doesn’t normally suffer from low blood pressure, but because he allowed himself to become dehydrated, his BP dropped and that’s what made him faint. Because there are few signs of low blood pressure, even a doctor noticed nothing, other than being thirsty and a little dizzy.
Blood pressure is the pressure your circulating blood applies to the walls of blood vessels. Most of the pressure is due to the heart pumping blood through the circulatory system.
When you are dehydrated, your blood volume drops, decreasing the flow and pressure.
Dehydration can also cause high blood pressure because the heart has to work harder to pump blood throughout your body.
Dehydration and Low Blood Pressure
Low blood pressure can be dangerous. If you’re dehydrated, the risk will increases. It's considered low if your BP reading is lower than 60/90. Some symptoms might include:
This is the feeling of slight dizziness and confusion.
The room feels like it’s spinning and you have to sit down because you feel like you’re going to fall over. You may feel sick. Some people may vomit.
Sometimes your brain switches off and you faint. With low blood pressure, you have less volume transporting blood and oxygen where it needs to go.
You will find it hard to focus on something either far away or close up, and the more you try, the harder it is.
5. Increased thirst
You may feel extra thirsty, especially if low blood pressure results from dehydration. It’s a never-ending cycle. You have low blood pressure due to dehydration, and low blood pressure increases dehydration.
Blood volume is important. It’s the amount of fluid that circulates in your blood vessels. The volume is important to reach all the organs and tissue that need it.
Dehydration leads to a lowering of blood volume, which causes blood pressure to decrease.
If your blood pressure drops too much, your organs don’t receive the oxygenated blood they require. You have the potential to go into shock — low blood pressure is to be avoided.
How to Handle Low Blood Pressure
If you are standing, and you experience one of the symptoms of low blood pressure, sit down, crouch down, or even lay down.
Some people find it beneficial to sit and put their head between their knees. Sit there for a few minutes until you feel better.
You could also bring your hydration levels up by sipping water. Don’t gulp large amounts because it may make you sick.
Other fluids you can rehydrate with include:
1. Water infused with fruit or vegetables
Try infusing your water with lemon or cucumber. Often infused water has a more cooling, hydrating effect.
Use your favorite fruits or vegetables in a smoothie.
Milk is good to sip because it’s cooling and it’s nearly 90 percent water.
Some fruits and vegetables are great for snacking on because they are water positive. They provide a good amount of water.Try cucumber, apple, orange or watermelon.
There are many good ways to ingest water daily.
Tips for dealing with dehydration
1. Try not to get thirsty. If you do, you are already dehydrated.
2. The more exercise you do, the more you need to drink. This is especially so if you sweat.
3. Always carry a water bottle with you so you sip water throughout the day. Try infusing fruit or vegetables if you don’t find water palatable.
4. Don’t drink sugary drinks like soda, energy drinks, sweetened beverages or alcoholic drinks. Many of them are diuretics, so they don’t hydrate you, but often dehydrate you. They cause you to excrete too much fluid.
Low blood pressure can result from dehydration. Your blood volume decreases and your organs won’t get the oxygen they need. Most people don’t link dehydration and low blood pressure.
Don’t go through the day without drinking water. When you are thirsty, you are already dehydrated, which sometimes can lead to low blood pressure, dizziness and fainting.
Have a bottle of water with you and sip throughout the day. Infuse your water with fruits or vegetables.
Avoiding dehydration is key to optimal health. If you get dehydrated and find yourself lightheaded, dizzy, or you have blurred vision, you may be experiencing low blood pressure. Sit or lay down and sip water slowly.
Remember, hydrating throughout the day is the best thing you can do for your body.
