Mavesyren

Mavesyren is the Swedish term for gastric acid, the digestive fluid produced by the stomach. In medical contexts it is referred to as gastric juice or gastric acid. The secretion comes from glands in the stomach lining and is composed mainly of hydrochloric acid, mucus, bicarbonate, intrinsic factor, pepsinogen, and various electrolytes. The acidity is high, with a typical pH around 1.5 to 3.5 when in the stomach, and daily production in healthy adults is approximately one to two liters.

Its primary function is to create an environment that denatures proteins, activates the proteolytic enzyme pepsin from pepsinogen, and assists in protein digestion. The acidic milieu also helps control ingested microbes and works with mucus and bicarbonate to protect the stomach lining.

Secretion is tightly regulated by neural and hormonal signals, including acetylcholine from the parasympathetic system, gastrin released by G cells, and histamine from enterochromaffin-like cells; somatostatin inhibits secretion. Pharmacological agents such as proton pump inhibitors and H2 receptor blockers can reduce mavesyren production, and factors like stress or Helicobacter pylori infection can alter acidity.

Clinical relevance includes disorders associated with abnormal acid production, such as peptic ulcers and gastritis from excess acid or mucosal damage, hypochlorhydria when acid production is low, and achlorhydria in rare cases. In medical literature and everyday use, mavesyren is often discussed in relation to digestion, gastric protection, and disease processes affecting the stomach.
