Many Americans need or already take blood thinners, and they can be a life-saving medication. At the same time, you may wonder what natural blood thinner options are for various reasons.
Using natural blood thinner options should never be a substitute for a medicine that your doctor prescribes. You should always speak to your doctor first and foremost about your health issues.
Some natural blood thinners may not work as effectively as prescription thinners, or if you use natural blood thinners with your prescription medication, it could create adverse side effects and interactions.
With that being said if you aren’t at the point where you need a prescription blood thinner, but you’d like some related health benefits, you might consider natural blood thinners instead.
What Are Blood Thinners?
Blood thinners are medicines that allow for the smooth flow of blood through your arteries and veins. Blood thinners can prevent blood clots from forming. They can also keep blood clots from getting bigger.
If you have some types of heart defects or disease, you may be at great risk of developing dangerous or deadly clots, so your doctor might put you on blood thinners.
While blood thinners can reduce your risk of stroke or heart attack, these prescription medications do have risks. For example, if you get a cut or a wound, you may bleed more than you would typically.
Types of Blood Thinners
There are two primary categories of blood thinners—anticoagulants and antiplatelets.
Anticoagulants work by preventing blood from clotting, and these are often taken as a pill.
Brand name blood thinners that are anticoagulants include:
Antiplatelets target the particles in the blood, which are called platelets. These include:
Blood thinners don’t really thin your blood or break up clots, but they can prevent the formation of new clots.
Anticoagulants work by competing with the vitamin K that comes from your liver. Your body requires vitamin K to make clotting factors, which are a type of protein. These clotting factors help platelets and blood cells bind together.
Antiplatelets prevent platelets from sticking to one another and your blood vessel walls. Antiplatelets are a weaker version of blood thinners than anticoagulants.
An estimated two to three million Americans take blood thinners annually. They’re often prescribed for people who have a history of heart attack or stroke, to prevent a recurrence.
If you have a blood vessel or heart disease, deep vein thrombosis, or lupus you might also be prescribed to take a blood thinner.
People who are overweight or obese are at greater risk of blood clots, as are individuals who recently had surgery or people with an artificial heart valve.
Some people take blood thinners for a few months, while others take them indefinitely.
The Risks of Blood Thinners
We want our blood to be able to clot to an extent, because if you hurt yourself that clotting prevents excessive blood loss. Since blood thinners prevent clotting, you can anticipate bleeding more than usual if you hurt yourself.
People who are on blood thinners have to be careful about their activities as a result.
With some blood thinners, your doctor will do regular blood tests to make sure you’re taking the right dosage.
Covid-19 and Blood Clots
We’re learning more about Covid-19 as the pandemic continues in the U.S. and worldwide.
There is some evidence that Covid-19 can cause changes in blood platelets, and that can lead to more severe outcomes when people are infected by the virus, such as strokes and heart attacks.
There are inflammatory proteins that are produced during infection with COVID-19, which researchers say make them “hyperactive.” That hyperactivity may mean someone is more likely to develop dangerous or deadly blood clots.
What Puts You At Risk For Blood Clots?
Clots occur in the arteries or veins, which are part of your circulatory system. When an abnormal clot forms in a vein, it can cause pain, and it can restrict blood flow to the heart. There is also a situation called a pulmonary embolism where a clot can detach and travel through the heart
Some of the risk factors for developing blood clots include:
- Oral contraceptives
- Certain cancers
- Being over the age of 60
- Having a family history of blood clots
- Chronic inflammatory diseases
- High blood pressure
- High cholesterol
What Are the Symptoms of a Blood Clot?
Some of the symptoms of a blood clot can include chest pain or heaviness, or discomfort in the upper body, shortness of breath, sweating, light-headedness, and nausea. These symptoms may indicate a blood clot in or near the heart.
A brain blood clot can include symptoms like weakness of the face or limbs, problems speaking, vision trouble, headaches, and dizziness.
In the arm or leg you might experience pain that’s sudden or gradual, swelling, warmth, and tenderness.
In the lung, you may feel a racing heart, shortness of breath, sweating, coughing up blood, fever, or sharp pain in the chest.
Blood clots in the abdomen can create symptoms like severe pain, diarrhea, and vomiting.
Risks of Prescription Blood Thinners
While you should always listen to your doctor as far as any medications and let them know of side effects you may experience, some are possible with blood thinners.
Some of the most commonly experienced side effects of blood thinners include:
- Some people may experience low red blood cell counts when they’re on a blood thinner which can mean anemia. Symptoms of anemia can include weakness, fatigue, dizziness and shortness of breath.
- You have to be sure you let your doctor know about any other medicines or supplements you take along with blood thinners to avoid potentially dangerous interactions. For example, antifungal medications and some antibiotics can strengthen the potency of blood thinners and increase your risk of bleeding.
- Don’t skip a dose of your blood thinner ever, and if you forget to take it for a day, speak with your doctor about what you should do.
- Keep an eye out for signs of internal bleeding. Symptoms of internal bleeding may include pale skin, stools that look black or tarry, fatigue, and shortness of breath.
- You have to be very careful to avoid trauma such as falls or cuts when on blood thinners because you could experience significant bleeding.
- You aren’t supposed to drink alcohol with blood thinners because alcohol may impact how the medicine is processed in your liver, and it could increase the amount of medicine in your bloodstream.
