Bleeding, also known as haemorrhaging, is blood escaping from the circulatory system. A subconjunctival hemorrhage is a common and relatively minor post-LASIK complication. The endoscopic image of a type of stomach cancer known as linitis plastica. The leather bottle-like appearance can also cause bleeding as can be seen in this image.
There is typically no change in vital signs and fluid resuscitation is not usually necessary. The limit of the body’s compensation is reached and aggressive resuscitation is required to prevent death. This system is basically the same as used in the staging of hypovolemic shock. Individuals in excellent physical and cardiovascular shape may have more effective compensatory mechanisms before experiencing cardiovascular collapse. These patients may look deceptively stable, with minimal derangements in vital signs, while having poor peripheral perfusion. The World Health Organization made a standardized grading scale to measure the severity of bleeding.
Ovarian bleeding – this is a potentially catastrophic and not so rare complication among lean patients with polycystic ovary syndrome undergoing transvaginal oocyte retrieval. Bleeding arises due to either traumatic injury, underlying medical condition, or a combination. Traumatic bleeding is caused by some type of injury. There are different types of wounds which may cause traumatic bleeding. Abrasion – Also called a graze, this is caused by transverse action of a foreign object against the skin, and usually does not penetrate below the epidermis. Excoriation – In common with Abrasion, this is caused by mechanical destruction of the skin, although it usually has an underlying medical cause. Hematoma – Caused by damage to a blood vessel that in turn causes blood to collect under the skin.
Laceration – Irregular wound caused by blunt impact to soft tissue overlying hard tissue or tearing such as in childbirth. In some instances, this can also be used to describe an incision. Incision – A cut into a body tissue or organ, such as by a scalpel, made during surgery. Puncture Wound – Caused by an object that penetrated the skin and underlying layers, such as a nail, needle or knife. Contusion – Also known as a bruise, this is a blunt trauma damaging tissue under the surface of the skin. Crushing Injuries – Caused by a great or extreme amount of force applied over a period of time. The extent of a crushing injury may not immediately present itself. Ballistic Trauma – Caused by a projectile weapon such as a firearm. The pattern of injury, evaluation and treatment will vary with the mechanism of the injury.
Wounds are often not straight and unbroken skin may hide significant injury. Penetrating trauma follows the course of the injurious device. As the energy is applied in a more focused fashion, it requires less energy to cause significant injury. Any body organ, including bone and brain, can be injured and bleed. The underlying scientific basis for blood clotting and hemostasis is discussed in detail in the articles, coagulation, hemostasis and related articles. The discussion here is limited to the common practical aspects of blood clot formation which manifest as bleeding. Some medical conditions can also make patients susceptible to bleeding. Such conditions either are, or cause, bleeding diatheses.
Platelets are small blood components that form a plug in the blood vessel wall that stops bleeding. Platelets also produce a variety of substances that stimulate the production of a blood clot. There are several named coagulation factors that interact in a complex way to form blood clots, as discussed in the article on coagulation. Deficiencies of coagulation factors are associated with clinical bleeding. This medication needs to be closely monitored as the bleeding risk can be markedly increased by interactions with other medications. Warfarin acts by inhibiting the production of Vitamin K in the gut. Deficiencies of platelet function may require platelet transfusion while deficiencies of clotting factors may require transfusion of either fresh frozen plasma or specific clotting factors, such as Factor VIII for patients with hemophilia.

Is Fish Oil the Answer for Heart Disease, Diabetes? Hemorrhoids are swollen veins in the lowest part of your rectum and anus. Sometimes the walls of these blood vessels stretch so thin that the veins bulge and get irritated, especially when you poop. Swollen hemorrhoids are also called piles. Hemorrhoids are one of the most common causes of rectal bleeding. They’re rarely dangerous and usually clear up in a couple of weeks.
But you should see your doctor to make sure it’s not a more serious condition. He can also remove hemorrhoids that won’t go away or are very painful. Internal and External Hemorrhoids Internal hemorrhoids are far enough inside the rectum that you can’t usually see or feel them. They don’t generally hurt because you have few pain-sensing nerves there. Bleeding may be the only sign of them. External hemorrhoids are under the skin around the anus, where there are many more pain-sensing nerves, so they tend to hurt as well as bleed. Sometimes hemorrhoids prolapse, or get bigger and bulge outside the anal sphincter. Then you may be able to see them as moist bumps that are pinker than the surrounding area.
And they’re more likely to hurt, often when you poop. Prolapsed hemorrhoids usually go back inside on their own. Even if they don’t, they can often be gently pushed back into place. A blood clot can form in an external hemorrhoid, turning it purple or blue. It can hurt and itch a lot and could bleed. When the clot dissolves, you may still have a bit of skin left over, which could get irritated.
