The hematocrit level represents the quantity of red blood cells present in the blood. For adult men, this rate should be around 45% and for adult women, around 40%  X Source of research . The hematocrit level is a decisive factor in the diagnosis of certain diseases. Too high a hematocrit could cause you shock or hypoxia, a problem resulting from too little oxygen circulating in the blood. On the other hand, too low a hematocrit can lead to anemia or other problems resulting from insufficient oxygen circulating in your blood.
Change your diet
Avoid dietary supplements containing iron. To create red blood cells, your body needs a lot of hemoglobin. Iron is the best way for your body to make hemoglobin. Since red blood cells are the primary reason for high hematocrit level, do not take supplements containing iron.
If you are currently taking iron supplements, speak with your doctor to determine what is best for you.
Stay hydrated. Dehydration will result in an increased hematocrit in the blood, a higher amount of whole blood and plasma, because there will be less fluid in your body to dilute the blood. This means that when you are severely dehydrated, your hematocrit will be very high, but on the other hand, if you have enough water in your body, your hematocrit will remain normal.
Coconut water, single fruit juices (such as apple or pineapple juice) and sports drinks (such as Gatorade or Powerade) are also good choices.
Remember that 8 to 12 glasses of water a day will do wonders for your body. Make a habit of it to increase your fluid intake, especially if you’re in the middle of strenuous activity.
Know the drinks you should avoid. It is not recommended to drink drinks that contain caffeine or alcohol, as they are both diuretics. They stimulate urine production and can make you dehydrated even if you don’t drink them constantly. If you want to keep your hematocrit level low, avoid soda, wine, hard liquor and beer and stick to drinking water and unsweetened fruit juices.
By drinking more liquids, the concentration of your blood will be more diluted, because your body retains liquid in your blood, which in turn lowers the concentration of hematocrit. Set yourself a consumption of 2 liters of water per day or more to maintain a normal level of hematocrit.
Eat a grapefruit every day. Recent studies have shown that eating half a grapefruit a day can lower hematocrit levels. The higher this rate, the more effect the grapefruit will have. Add half a grapefruit to your breakfast and eat the other half as a snack.
Grapefruit contains naringin, a flavonoid in high concentration, which causes phagocytosis, a natural process that eliminates red blood cells from the body and converts them for other purposes.
Consume more antioxidants. These help your body protect itself against free radicals thought to be responsible for cancers and other blood diseases. When you consume dietary supplements or foods rich in antioxidants, your body can more easily transport oxygen. You will find good sources of antioxidants in plums, beans and berries.
Antioxidants help you in so many ways, but the most important thing to note when it comes to lowering your hematocrit is that antioxidants help the blood take in more oxygen so that it can circulate better in the body. They not only help to prevent diseases, but they also help to keep you healthy.
Change your habits
Exercise in moderation. It is important for your health to exercise, but do not overdo it, as it can raise your hematocrit level. You can for example do:
mowing the lawn
Donate your blood. According to the NHS Blood and Transplant , blood donors should only donate 4 times a year or with a 12 week interval between donations. Only do this as a last resort and after consulting your doctor. If he approves of your decision, donating blood will be useful to you for the following reasons.
This helps clean the blood, as your body will try to compensate for the amount of blood that has been lost and will circulate fresh blood.
This rids you of excess iron in your body. It is believed that excess iron in the blood causes atherosclerosis, a thickening of the walls of the arteries. When you donate blood, approximately 250 mg of iron will be removed from your body, which helps lower the risk of developing cardiovascular disease.
Take aspirin. Again, only do this as a last resort, as it may come with side effects. Make sure you have your doctor’s permission before taking aspirin to lower your hematocrit, as aspirin will lower your hematocrit causing gastrointestinal bleeding .
Aspirin is a substance that destroys platelets. Platelets allow blood to clot after an injury. When you take aspirin to lower your hematocrit, be aware that it can thin your blood and make it unable to clot, accompanied by mild headaches and other neurological disorders.
Stay near sea level. Areas at higher elevations have a lower oxygen concentration than areas near sea level. An area above 2,400 meters is considered oxygen deficient . People who live in these areas generally have higher hematocrit levels. You can get your hematocrit back to normal by moving to a lower area.
In response to its environment, the bone marrow, which is responsible for the production of hematocrit, has adapted to produce more hematocrit to compensate for the lack of oxygen in the body and this is why there is a higher level of hematocrit in the blood.
Stop smoking . The nicotine contained in cigarettes and other tobacco products impairs blood circulation by reducing the ability of red blood cells to carry oxygen. The body then compensates for the lack of oxygen in the blood by producing more red blood cells in the bone marrow, which then increases the amount of hematocrit in the blood. Stop smoking or consuming tobacco products to lower the hematocrit level in your blood.
Quitting smoking is also good for your heart, your lungs, your skin, your hair and your whole body. On top of that, it’s also better for those around you. If you can’t stop just to lower your hematocrit, consider these other reasons.
Address the problem at the root. A high hematocrit could be the result of a disease, for example certain varieties of cancer or even a tumor. Tumors and cancers, especially those of the bone marrow, create an uncontrolled production of red blood cells.
Do not jump to the conclusion that you have cancer if your hematocrit level is too high. The best way to find out how to lower your hematocrit and why it is so high is to see your doctor.
Symptoms of a high hematocrit
Watch your headaches and dizziness. Both of these symptoms are the result of too high a hematocrit in the blood, which makes your blood more concentrated. Headaches and dizziness are signs that your body is trying to compensate for this abnormal hematocrit level.
Concentrated blood is viscous, that is, it is thicker and more sticky and does not flow well. This causes a poorer oxygen supply to the brain, which can become a very serious condition quickly.
See your doctor if you feel weak and tired. It could be your body’s response to more viscous blood that can no longer deliver oxygen and nutrients to the rest of the body properly. If you feel weak all the time, see your doctor as soon as possible. Only a health professional can tell you what to do.
Fatigue can come from different things, not just from a high hematocrit level. To determine the reason why you are tired, you must consult your doctor, only a medical professional can help you.
Pay attention to your breathing. People who have a higher hematocrit often suffer from tachypnea . It is a medical term for rapid breathing of more than 20 cycles per minute. It is a short-term compensatory mechanism in response to poor oxygen supply.
Again, taken on its own, this is not a symptom that should panic you. Only if you find that your breathing is quickening more often than usual for no logical reason should you ask yourself questions.
Watch for bruising. A high hematocrit could cause bruising due to the high concentration of blood flowing through your veins. Viscous and concentrated blood tends to form clots on any part of the body. The bruises will show up as purple or black spots on the skin. Some won’t hurt you while others will be tender to the touch.
A bruise is also the natural result of a shock. The bruises you need to watch out for, especially when you have doubts about your hematocrit level, are the bruises that seem to have appeared for no reason. If you have bruises that appear out of nowhere, they could be hematocrit bruises.
You have strange sensations in the skin. A high hematocrit level can cause many inexplicable sensations in your skin. Blood flowing just under your skin, when it lacks oxygen, can interfere with your sensory receptors. Here’s how.
Itching sensations . Itching is caused by histamine created by the body in response to too high a hematocrit level. Histamine is a chemical messenger that comes into play during inflammations and allergies. Itching will first occur on the extremities, hands and feet.
paresthesia . This describes a tingling, tingling, or burning sensation in the palms of the hands and the soles of the feet. The root cause is poor blood circulation. A high hematocrit level makes the blood more viscous due to the high concentration of red blood cells in the blood plasma. It is also a common symptom in patients suffering from diabetes with poor blood circulation.
