1.1. ANEMIAS DUE TO Blood LOSS (POSTHEMORRHAGIC)

Posthemorrhagic anemias are classified into acute and chronic forms.

Acute posthemorrhagic anemias occur following massive blood loss resulting from vascular rupture due to trauma, or erosion of vessel walls caused by a gastric ulcer, Ectopic Pregnancy, or tuberculosis.

Chronic posthemorrhagic anemias develop As a result of gradual blood loss over an extended period from disintegrating tumors, hemophilia, hemorrhoids, PEPTIC ULCER DISEASE, or uterine bleeding in women, among other causes. Such anemias are invariably hypochromic due to depleted iron reserves.
