Our papa needs medical help

My papa was diagnosed with diabetes for 10 years now. But last June 2018, we didn't know that he was already having a heart attack until he was rushed to the hospital. Several tests and examination has been done to him. And found out that he was already having complications due to diabetes. He was diagnosed with pneumonia that he went for six months continuous medication. And from time to time needs to remove water from his lungs. Coronary Andiogram took place also to check the heart condition and the damage and as per the result "severe left main and three vessels coronary artery disease, Recommendation is via CABG (Coronary Artery Bypass), and as we have checked it will cost us 700,000 - 1,000,000 pesos. Aside from this, now he is going through another condition where his whole body is getting swollen including his private part. He needs urgent medical attention and my family cannot afford all these expenses as we have been supporting all his medications and going to the hospital every now and then. I am an regular OFW and unable to provide all the financial needed to help my father recover. Our family is knocking to all the kind hearts to please help and support us as we would want our father to still recover. Your support will help us to send him for heart operation and currently he needs to be rushed again to the hospital due to his swollen half body (including his private part) as the doctor said this may be because of kidney. God bless all and praying that we will be able to overcome this through your help and support. Thank you.
