吐黑水可能是呕血,可能是非病理因素如饮食不当引起的,也可能是病理因素如胃溃疡、急性糜烂性胃炎、食管胃底静脉曲张出血或其他因素所致,建议患者应及时前往医院就诊,明确原因后给予针对性治疗,以免延误病情。
一、非病理因素
1、饮食不当
如果患者大量饮用凉茶、黑豆水等颜色较深的食物,可能导致出现呕吐、呕黑水的现象。此时一般为饮食不当引起的,无需特殊治疗,多加休息即可。
二、病理因素
1、胃溃疡
胃溃疡与胃酸分泌过多有关。胃溃疡患者若出现溃疡出血,可有餐后腹痛、呕血、黑便等症状。

患者可根据医嘱使用抑制胃酸分泌的药物,如法莫替丁、尼扎替丁等。还可根据医生指示使用质子泵抑制剂,如兰索拉唑、泮托拉唑等。
2、急性糜烂性胃炎
急性糜烂性胃炎与药物的不良反应、酗酒等原因有关。此时可破坏胃黏膜,患者可出现上腹疼痛、腹胀、贫血、反复呕血等症状。

患者应停止使用损伤胃部的药物、停止饮酒。胃黏膜糜烂严重患者,可使用胃黏膜保护剂,常见的药物有硫糖铝、替普瑞酮等。
3、食管胃底静脉曲张破裂出血
此病通常与门脉高压有关。门静脉高压时,患者可出现食管胃底静脉的迂曲、扩张。饮食不当、病情加重等因素可诱发其破裂出血。一般出血量大,患者还可有头晕、乏力、便血等症状。患者可根据医嘱使用药物进行治疗,如奥美拉唑等质子泵抑制药、垂体后叶素等以止血。药物治疗无效患者,可采取贲周血管断流术或胃大部切除术等方法进行治疗。
4、其他因素
另外,上述症状也可能是由于胃癌引起的,由于炎症刺激可出现腹痛、呕血、消瘦等症状的发生。可根据医生指示使用靶向药物治疗,如曲妥珠单抗、甲磺酸阿帕替尼等。
患者出现上述症状时,应立即去医院消化内科就诊,进行相关的检查,明确病因后遵医嘱治疗。
