This causes the hemorrhoidal tissue to shrink over time, alleviating symptoms such as pain, bleeding, and swelling. [ 1 ] [ 2 ] [ 4 ] Post-procedure, patients are monitored for a brief period to ensure stability before being discharged with instructions for managing any minor discomfort or symptoms that may occur during the recovery period.
Internal hemorrhoids are inside your anus and painless but can cause bleeding during bowel movements. External hemorrhoids occur when hemorrhoids are pushed just outside of the anal opening.
Internal and external hemorrhoids may present differently; however, many people may have a combination of the two. [8] Bleeding enough to cause anemia is rare, [5] and life-threatening bleeding is even more uncommon. [15] Many people feel embarrassed when facing the problem [5] and often seek medical care only when the case is advanced. [8]
Often, the first approach is to use endoscopy to look for obvious signs of a bleed. In cases where the source of the bleed is unclear, but melena is present, an upper endoscopy is recommended, to try to ascertain the source of the bleed. [citation needed] Lower gastrointestinal bleeding sources usually present with hematochezia or frank blood.
Common causes of lower gastrointestinal bleeding include hemorrhoids, cancer, angiodysplasia, ulcerative colitis, Crohn's disease, and aortoenteric fistula. [2] It may be indicated by the passage of fresh red blood rectally, especially in the absence of bloody vomiting. Lower gastrointestinal bleeding could also lead to melena if the bleeding ...
A multiple vehicle collision (colloquially known as a pile-up or multi-car collision), [1] is a road traffic collision involving many vehicles. Generally occurring on high-capacity and high-speed routes such as freeways, they are one of the deadliest forms of traffic collisions. The most disastrous pileups have involved more than a hundred ...
Because of the way detonation breaks down the boundary layer of protective lubricant surrounding components in the cylinder, such as the spark plug electrode, these components can start to get very hot over sustained periods of detonation and glow. Eventually this can lead to the far more catastrophic pre-Ignition as described above.
This is most likely to occur on a carbureted engine in cold weather, after a running engine has been shut off briefly before being restarted. Doing so can cause the choke valve to configure the mixture for a cold engine start, despite higher actual temperatures, resulting in an overly rich mixture and flooded engine.
