疝气 HERNIA

很多人都不懂什么是hernia吧！
在这里告诉大家..
我也说到嘴酸..
而且你们听了也似懂非懂....

疝气
医学名词,即人体组织或器官一部分离开了原来的部位,通过人体间隙、缺损或薄弱部位进入另一部位详细解释
通常指腹股沟部的疝。因小肠通过腹股沟区的腹壁肌肉弱点坠入阴囊内而引起，症状是腹股沟凸起或阴囊肿大，时有剧痛。也称小肠串气。

HERNIA
By far the most common herniae develop in the abdomen, when a weakness in the abdominal wall evolves into a localized hole, or "defect", through which adipose tissue, or abdominal organs covered with peritoneum, may protrude. Another common hernia involves the spinal discs and causes sciatica.
Herniae may or may not present either with pain at the site, a visible or palpable lump, or in some cases by more vague symptoms resulting from pressure on an organ which has become "stuck" in the hernia, sometimes leading to organ dysfunction. Fatty tissue usually enters a hernia first, but it may be followed by or accompanied by an organ.
Most of the time, herniae develop when pressure in the compartment of the residing organ is increased, and the boundary is weak or weakened.
Weakening of containing membranes or muscles is usually congenital (which explains part of the tendency of herniae to run in families), and increases with age (for example, degeneration of the annulus fibrosus of the intervertebral disc), but it may be on the basis of other illnesses, such as Ehlers-Danlos syndrome or Marfan syndrome, stretching of muscles during pregnancy, losing weight in obese people, etc., or because of scars from previous surgery.
Many conditions chronically increase intra-abdominal pressure, (pregnancy, ascites, COPD, dyschezia, benign prostatic hypertrophy) and hence abdominal hernias are very frequent. Increased intracranial pressure can cause parts of the brain to herniate through narrowed portions of the cranial cavity or through the foramen magnum. Increased pressure on the intervertebral discs, as produced by heavy lifting or lifting with improper technique, increases the risk of herniation.
