Does grapes thicken the blood?
Patient: My mom who is 86 has been on Warfarin now for 18 years.  All of a sudden recently, her blood has been either way too thin or she is at the extreme opposite of being way to thick.  I would like to know if grapes are a blood thickener because she craved grapes for about 2 weeks and ate them all day long. Doctor: Hello dear,Thank you for your contact to health care magic.I read and understand your concern. I am Dr Arun Tank answering your concern.No, it's your belief that grapes can thicken your blood.Warfarin is usually given to thin the blood as in your mothers case. If excessive warfarin is taken on the blood than blood can be thinned out.If blood goes much thin than Vitamin K can be taken to revert the effect of the warfarin. Please take the above treatment under your doctors guidance as its requires constant monitoring of INR value of anticoagulant.I will be happy to answer your further concern on bit.ly/DrArun.Thank you,Dr Arun TankInfectious diseases specialist,HCM.
