Blood is normally about three times thicker than water. With thick blood problems it can be up to ten times thicker than water.

I know of someone in my past years who had to give blood once a month until the blood thinned out upon testing by the doctor who ordered it.

She gave about a pint a month. I assume they dispose of it, I don't know. Some nationalities have a tendency also to have thick blood.

Your doctor will be able to assist you if you do have this problem. There are medications too for this, besides having blood taken at regular intervals.

Don't assume you have the very worst. Wait for a doctor to declare it and give you a dx. If you are heated, or have a temperature, your blood will be thicker too.

I think red wine thickens it too but don't hold me to that. My grandmother used to say that. She came from a very cold northern climate and took a small amount of red wine to make her blood thicker to withstand the cold. This could be one of those old wives tales that worked, who knows. But not good for you.

So diet may pay a part in this too. They say dizziness, nausea, headaches and blurry vision can happen with thick blood if you lack some Oxygen to body.

I hope you get tested to be sure. Good luck to you. This is all just my opinion. I am not a doctor.
