Certain illnesses, such as cutaneous porphyria, yellow fever, and Von Willeband's disease, cause bleeding pores in some people who already have low amounts of specific proteins that allow the blood to clot sufficiently. Bleeding pores can sometimes be a side effect when the pathogens or enzymes associated with these diseases are strong enough to break down the regular function of blood platelets. A medical condition called hematidrosis can also cause bleeding through pores in a manner similar to sweating. This health problem is normally quite rare and only manifests during times of intense emotional or physical stress. A small number of individuals who have this condition with no medically apparent cause are usually diagnosed with idiopathic Type II platelet disorder.
Imbalances of enzymes in the structure of the blood's iron molecules can sometimes lead to a subcategory of porphyria that physicians designate as cutaneous because it primarily affects the skin's normal function. This condition has various symptoms, such as dark discolorations of the skin, extreme sensitivity to sunlight, receding gums, and even decomposition of the skin. Signs of this porphyritic-induced tissue death can include bleeding through the skin along with swelling, itching, or pain.
Outbreaks of yellow fever can develop in people bitten by mosquitoes carrying the disease's harmful bacteria. Physicians classify this medical condition as a hemorrhagic viral infection that can be particularly dangerous in patients with previously weakened immune systems. Severe yellow fever infections can disrupt liver function and cause significant internal organ hemorrhages. Signs of this uncontrolled hemorrhaging can include bleeding pores in some cases.
Some rare cases of Von Willeband's disease can cause bleeding pores when levels of blood-clotting proteins are very low and the blood is thin in consistency due to improper platelet function. Hematidrosis is another medical condition associated with blood seeping through the skin. This disorder triggers bleeding pores when clusters of capillaries around each sweat gland rupture due to heightened blood pressure. Medical experts often report that people with hematidrosis normally experience its symptoms along with feelings or extreme fear or anxiety.
Type II platelet disorder is a rare cause of bleeding through the pores with no apparent underlying disease or disorder. Individuals who are not suffering from an infection, such as yellow fever or an inherited condition like Von Willeband's disease, can still regularly bleed through their skin. They typically do not feel any pain during these episodes, although the risks of anemia and physical deterioration from the blood loss can be high.
