严重的胃病英语怎么说呢

严重的胃病英语称为"severe gastric disease"。它可能来自于不良的饮食习惯，比如过度摄入高脂肪或高盐食物。也可能是由于细菌感染或内部组织损伤导致的。例句如下：
"He was diagnosed with severe gastric disease and had to undergo surgery to remove part of his stomach."
他被诊断出患有严重的胃病，不得不接受手术，切除部分胃。
"She had been suffering from severe gastric disease for many years and had to follow a strict diet to control her symptoms."
她长期患有严重的胃病，不得不遵循严格的饮食规定来控制症状。
