10.8 Health Issues Related to The Lymphatic System of Humans
 
Edema is caused by the excess fluid that is trapped in the body tissues, which is usually caused by the leaking of interstitial fluid from the blood flow. 
 
Causes of edema:
 
  • Pregnancy: The body will produce more body fluid to fulfill the needs of a growing fetus.
  • Prolonged bedridden patients: Paralysed or stroke patients with limited mobility can suffer from edema in the legs.
  • Deficiency of plasma protein: Deficiency of albumin in the blood.
  • Parasitic infection:
    • The parasite worm Brugia sp. infects the lymphatic vessel and prevents the flow of lymphatic fluid.
    • The infected part, for example, leg will swell.
    • The patient contracts lymphatic filariasis.
    • This worm is transmitted through mosquito bites.
