Can you please describe the diseases associated with blood group o+?

Can you please describe the diseases associated with blood group o+?

Basically none: Even the classic link to stomach ulcers isn't holding up well nowadays. There are a couple of charlatans who have written some books suggesting that different blood group people should practice different diets, habits and so forth. It's made up and isn't science. ...Read more

Im 23 yr old, I weight 90kg after giving birth.Im 5 ft 3inch.Im of blood group o.What is suppose to be my weigh n how do I trim down in 4 months ?

About 20 kg: There is no perfect answer for everyone. Do weight watchers. Exercise everyday. A rough guide is that for women, you start at 100 pounds at 5 feet and add five pounds for every inch above 5 feet. So if you are 5 ft 3in, you should weigh somewhere between 115 pounds and 130 pounds. ...Read more

How can you tell if a newborn with blood group o has antibodies for both a and b antigen?

Blood group antibody: At birth a kid with blood group o negative will have no original antibodies to any blood group. There may be some transient anti-a or b passed along with shared maternal antibodies, but these will disappear over a few months. Specific testing might detect them, but for no real benefit. In life we can develop original anti a or b from things we eat. ...Read more

Can parents of blood group o positive give birth to an as positive baby? And if this happened, what could be the potential causes?

Can parents of blood group o positive give birth to an as positive baby? And if this happened, what could be the potential causes?

Yes. Different genes: Blood type o has nothing to do with hemoglobins a and s. That two parents have a child with sickle cell trait (hemoglobins a and s) indicates that at least one of the parents has sickle cell trait. I would predict that the child's blood type is o. ...Read more

Perhaps some of my teammates in gastroenterology can clarify. ...Read more
