Hi. This is in connection with my general inquiry about my father's blood CPR results. He is 60 years of age and is currently have diabetes. Actually he was getting weaker day by day that's why I insisted him to have his blood, urine and stool test. The reports revealed all other things quite normal except ESR 53mm/hour in blood. I want to know what does that mean? And whether it is indicative of any serious disease. Can anyone please advice? And other commonly symptoms include weight loss, decreased appetite, excessive cough, muscle weakness and fatigue. I am extremely worried about his health as he retired the same very year. I am thinking whether he is stressful maybe that's the cause. But I would be thankful if anyone can sincerely advice including any natural remedy that someone can propose?
