The low bp that results causes a loop of hormone reactions that will cause the heart rate to go up to compensate for the lower blood/oxygen flow to critical areas— like the brain. The result of this increased heart rate is that the heart muscle, initially starved for oxygen will continue to wear itself out compensating. It is a vicious cascade of natural events that leads to death without intervention. You can't replace damaged heart muscle and get it back up to full function— you can only try to assist the body with agents to reduce the amount of stress on the organs from this, and reduce the amount of fluids that build up.
Hey, thank you for this information. I have a friend (woman) that has been almost 3 years sober having problems like this with low blood pressure. Then it will shoot up at times.
She had been drinking since she was about 12-13 years old and stopped at 40.
Had to have been some damage done in all that time especially the developing years of adolescence.
