Despite the name, watermelon stomach is not a pleasant medical condition, by any means, and due to its severity, it is important to be able to recognize the symptoms and causes of this unusual disorder.
Diagnosis of Watermelon Stomach
Diagnosing watermelon stomach can be achieved through various tests, such as an endoscopy, biopsy, and ultrasound, among others.
This approach to diagnosis may involve sending a small tube with a light and camera into the gastrointestinal system to see whether the characteristic stripes and bleeding are present in the stomach. 
A biopsy may consist of removing a small piece of tissue from the affected part of the body to determine whether it has been infected by a specific disease.
An ultrasound allows doctors to image the final section of your stomach, where it can identify swelling and dilation of blood vessels that signify this condition.
Treatment for Watermelon Stomach
To eliminate watermelon stomach, the best options may include surgery, certain medications, and even blood transfusions, as well as dietary alterations.
Surgery – Endoscopic laser surgery will help to seal up ruptured blood vessels. Argon plasma coagulation is another treatment option that can seal up ruptured and bleeding tissue. 
Medication – Corticosteroids have been shown to be somewhat successful, as well as hormone therapy, to minimize the symptoms of this condition.
Diet – You should change your diet to avoid harsh, acidic foods. Eating a lot more soups and smoothies can give your stomach a break; you should also avoid caffeine and alcohol until the symptoms subside.
Transfusions – If a significant amount of blood has been lost, transfusions may be required to offset the blood loss.
