blood thickening reasons - #16783
I am really worried about my health lately. Few months ago, I started noticing I was feeling more fatigued than usual, and I've been getting these weird headaches, which I never had before. After a visit to the doc, they mentioned something about blood thickening reasons, and I'm trying to wrap my head around it. I had some tests done, and they mentioned my blood viscosity was off. Like, what does that even mean? I thought it was just me getting older or not drinking enough water, but now I’m not sure. I've been trying to eat healthier since then, but I still don’t understand the blood thickening reasons that could be causing this. I mean, is it just diet or could there be other hidden factors? My doctor said something about genetics too, which sounds a bit scary... How much do you think family history plays into the blood thickening reasons? And what kind of lifestyle changes should I be looking into? Like, will just drinking more water help, or do I need to address something bigger? I’m just a bit confused about what I need to do to avoid any serious issues because of these blood thickening reasons. Anyone else dealt with this? What did you guys do?

Doctors’ responses
Blood thickening, or increased blood viscosity, can indeed be influenced by a variety of factors, like lifestyle, diet, and genetics. Its interesting that this is a concern for you now and understanding the underlying reasons is important. First, let’s consider the physiological causes. Blood viscosity can be affected by the number of red blood cells, white blood cells, and platelets in your blood, which is why conditions like polycythemia (excess of blood cells) can lead to thicker blood. Chronic dehydration, which you mentioned, can also play a role because less fluid leads to more concentrated blood, exacerbating its thickness.
Genetics can significantly contribute as well. Conditions like essential thrombocythemia or polycythemia vera are blood disorders that are inherited and lead to increased blood cell production. It’s important to discuss with your doctor if there’s a family history of blood disorders. Diet can also affect blood viscosity. Foods high in saturated fats, trans fats, and sugars, for example, can increase cholesterol levels, affecting blood flow. Eating a balanced diet rich in omega-3 fatty acids, antioxidants, and fibers can help reduce risk. Keeping hydrated by drinking adequate water—though it’s simple— can help thin your blood, but it’s often not the sole solution if blood viscosity is significantly altered. Lifestyle changes are crucial, including regular physical activity, maintaining a healthy weight, and avoiding smoking, all of which can contribute to healthier blood flow and reduce viscosity.
Additionally, it might be helpful to look into medications that might be contributing to blood thickening. Some medications can affect blood viscosity, and it could be worth a review with your physician. Sometimes, anticoagulant medications might be needed, depending on the specific circumstances and the risk factors present in your case. Always follow up with your healthcare provider for a tailored management plan, since uncontrolled blood thickening can lead to complications like an increased risk of clotting, so it’s essential to be careful.
