Hi Im a 64 year old black women.  My grandfather, aunt and brother died of renal failure and other related illness. In 2003 I was told I too and a kidney and liver problem.  My kidneys at this time are okay put my liver has started to enlarge again I was once told it was around 138 and that it had gotten better it was at 78 ( I can not remember what I was told these figures mean). Since July my blood pressure has been 173/154. 69    129/89. 72 last week I went to the clinic it was totally perfect.  My medicine is Hydrochlorothiazide 12mg   I was give 20mg and it took me down to 69/69 65 I told the doctor and I stopped taking them.  I feel light headed when I wake in the morning my stomach feels sick and if it does not go away then I am like that for most of the day.  I have started to feel tired I am working on my master degree and I dont have time for this.  I also have hype C believe I got that maybe in 1966 or 1968 I had blood transfusion after child birth or in 2000 when my brother bite me and I did not know he was infected back then.  Thank you for listening

HI, thanks for using Chat Doctor Hepatitis infection can cause only acute changes in the liver or be associated with chronic liver disease. It may have contributed to the increase in your liver enzymes (those are likely the values you were quoting). High blood pressure increases the risk for kidney disease and if you are able to maintain it within a normal range it would reduce the chance of renal disease. If you have any additional risk factors such as diabetes, it would be important to control these as well. The low blood pressure readings may cause the lightheaded feeling. Nausea can be due to different causes such as :a side effect of medication, infections, alcohol, migraine, vertigo, liver disease, kidney disease. You should consider visiting your doctor for an assessment regarding the persisting nausea. Hope this helps
