First system in very high blood pressure.. not treated causes TIA or worse stoke of the brain. Nor all will know they have high blood pressure unless you go to doctor. I was pregnant with first child at 19 yrs of age and told had to go on "NO SALT" diet including pork. Had 3 m children and told the same thing, high blood pressure which the doctor attributed to being pregnant and eat salt which I did not. Always had headaches severe at time taking mega doses of aspirin. God is so good because I accidently found out my blood pressure was 210/140 at age 27 yrs old in 1977. had 3 children 2 yrs 10 months, 5 yrs 2months and 7yrs 7 months. I was hospitalized in June 1977 at Height Hospital in Houston,Texas. After a Week in Hospital had a stoke ( which I was in coma 3 days with no side effects. I think it is called today TIA) Had a IVP showing blockage and that is all that was said. After about 2 weeks was sent to Herman Hospital, UTMB, Houston Texas. Had a test that they took blood right out of kidneys and 24 hour urinalysis and a test that they put radiation in artery to see kidney.IVP showing right kidney very small and artery had beading effect. After about 2 weeks I had a renal arterial bypass to the right kidney that DID NOT TAKE! 11 hour surgery. I was used as a trial and error. Just started doing kidney transplants in Herman UTMD. Very hard recovery and still have high blood pressure. I have had only the left kidney since 1977, Forty-one (41) years as gone by and take 3 blood pressure pills in a 24 hour period. Left renal is in stage 3 renal failure now. Eat no salt, pork, prepared foods, can foods, no coldcuts limited eating in restaurants, no cheese, no milk no beef. I eat chicken turkey and fresh water fish. Now if you think I follow that 100% I do not but I do follow almost 100%. I am almost 69 years old and by the grace of God I am still here in the world. I guess God is not through with me yet. Here to help others.
