  • Hemolytic crisis – acute hemoptysis in the context of anemia (anemia).
  • Hemophilia (hemophilia).

Endocrine, nutritional and metabolic diseases (E00-E90).

  • Addisonian crisis – decompensation of insidious adrenocortical insufficiency (adrenal insufficiency).

  • Diabetes mellitus (pseudoperitonitis diabetica).
  • Familial Mediterranean fever (FMF; synonym: familial recurrent polyserositis) – autosomal recessive inherited disease clustered in inhabitants of the eastern Mediterranean region; chronic disease characterized by sporadic episodes of fever with concomitant inflammation of the tunica serosa, resulting in abdominal pain (abdominal pain), thoracic pain or arthralgia (joint pain).
  • Hemochromatosis (iron storage disease) – genetic disease with autosomal recessive inheritance with increased deposition of iron as a result of increased iron concentration in the blood with tissue damage.
  • Hyperparathyroidism (parathyroid hyperfunction).

  • Food intolerance such as lactose intolerance, fructose intolerance.
  • Porphyria or acute intermittent porphyria (AIP); genetic disease with autosomal dominant inheritance; patients with this disease have a 50 percent reduction in the activity of the enzyme porphobilinogen deaminase (PBG-D), which is sufficient for porphyrin synthesis. Triggers of a porphyria attack, which can last a few days but also months, are infections, drugs or alcohol. The clinical picture of these attacks presents as acute abdomen or neurological deficits, which can take a lethal course. The leading symptoms of acute porphyria are intermittent neurologic and psychiatric disturbances. Autonomic neuropathy is often in the foreground, causing abdominal colic (acute abdomen), nausea (nausea), vomiting or constipation (constipation), as well as tachycardia (heartbeat too fast: > 100 beats per minute) and labile hypertension (high blood pressure).
