Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice. Flaxseeds might lower diastolic blood pressure. Theoretically, taking flaxseeds might cause blood pressure to become too low in individuals with high blood pressure who are taking blood pressure-lowering medication. Partially defatted flaxseed (flaxseed with less alpha linolenic acid content) might increase triglyceride levels. If your triglyceride levels are too high, don’t take flaxseed. Hope I have answered the question. Let me know if I can assist you further.
