Why humans can get hemorrhoids(piles) not other animals or living things?

Actually, some animals can get hemorrhoids. The link below advertises "natural remedies" for pet hemorrhoids! I kid you not.\n\nHumans, and pet animals, are more prone to hemorrhoids because of their diet. If you're out eating a "natural" diet, tons of insoluble fibre etc., you don't have to strain as hard to pass waste. Humans are especially prone because of our tendency to be upright, and to sit; these positions limit drainage from the rectal veins.

It is a condition where there is bleeding from the annus  due to swollen veins around the anal cannal. In the initial stage there is fistula or fissure which later develops in hemorhoids. Although piles is very painful, the treatment and permanent cure is a simple surgery (where the patient has to be hospitalized for 4/5 days). The market offers a wide vareity of ointments and oral tablets for piles but rarely providing permanent relief.\nThe reasons for hemorrhoides could be chronic constipation, pregnancy, over weight, hernia etc. (Mostly due chronic constipation - that is hard stools damage the soft lining of the anal cannal).

What we call the appendix in humans is called the gut caecum in other mammals.\n\nMammals can’t digest cellulose, what we commonly call plant fibre. As a result they can’t get any energy out of eating grass or leaves. But, I hear you say, plenty of mammals eat grass and leaves. But they don’t really. They just SWALLOW the grass and leaves.  Microbes in the animal’s gut cause the leaves to rot and the mammals then digest the microbes. So in a very real way horses and cows eat microbes, they just swallow grass.\n\nThe longer plant material sits in the gut the more time the microbes have to make it rot and the more energy the animal can get. For animals that eat a diet high in fibrous plant material the gut caecum serves as a holding tank for the food material while  have a chance to make it rot.\n\nThe appendix in gorillas for example is quite huge, about 2 feet long IIRC. Compared to just a couple of inches in humans That’s because gorillas live on a diet extremely high in plant fibre, and we don’t. Rabbits and horses also have huge appendices.

If we're talking about humans, 0! We can't digest cellulose. If we're counting bacteria in termites in comsumption... Then it is a totally different question...

one reason may be that humans don't go running through the bush as other mammals to. onther reason is in the genes. Some mammals may have genes the control the growth of hair in some species. \n\nBut i like the thought of the first one. if we were having to run and catch our food or we had to sleep on the ground our hair may not be allowed to grow as long.

You are constipated as  well as having hard stools.  You need to increase your liquid intake and eat more fresh fruits and veggies as well as other high fiber foods.  Go to the store and pick up some colace aka docusate to help soften your stools and a fiber supplement such as metamucil, citrucel or benefiber.  Do NOT strain on the toilet as this can cause hemorrhoids.

They have their own STD. \n\nBut thinking more about your question, I would say I do not know. Because too little humans are sick zoophilics, who could try this way, no material for big generalisations. Besides they had to be bi- in certain sense, for could catch a disease afroma human nd transmit it to animal... \n\nSome theories say that HIV passed from apes, so why some viruses and microbes could not do be passed (including mutations) to animals? Really probable thing.

hemorrhoids are caused from a lack of Vitamin B6, take 10 mg at each meal until they go away...\nOnce they go away, don't keep taking so much because taking too much of one b vitamin will make you deficient in the other b vitamins, you should take a daily multi vitamin each day.\nPeople in studies that were going to have to have surgery took b6 and they disappeared.

Diet plays an important role in whether a person gets hemorrhoids.  High fiber diets increase "bulk" and allows your solid waste to move through easily. Low fiber diets tend to constipate you, then you strain, and the straining will provoke hemorrhoids.\n\nDrinking plenty of water will help keep your solid waste soft!\n\nToo much sitting, not just on the toilet will also provoke them.  Good exercise helps.  Hemorrhoids are related to varicose veins, and exercise helps keep varicose veins at bay.\n\nIf they are really bad, there are surgical and some less invasive things your doctor can do.

Because they do not have a gastrointestinal tract like higher animals do.

First of all the premise of the question is not entirely correct.  Insects do not have their anus between their legs.\n\nMost animals are descended from worm-like animals.  A worm, in its simplest form is a tube with a mouth at one end, a gut and an anus at the other end.  It is more efficient to put the mouth at the front (direction of travel), so it evolved that mouth is in front, anus is in the rear.  Animals descended from that worm ancestor kept the same basic arrangement.  When animals developed legs the anus remained at the rear because the arrangement seems to work out pretty well.

They do, but some animals have a higher tolerance than humans.  Think about it, how would you feel after you eat a rotten carcass or plants off the ground.

Digesting cellulose requires Cellulase which is not secreted by mammals...only bacteria\nWe dont have cellulase secreting bacteria in our gut (cows have them,probably in their appendix)

Hemorrhoids (also known  piles) are varicosities or swelling and inflammation of veins in the rectum and anus.\n\nTypes and symptoms of hemorrhoids\n\nExternal hemorrhoids are those that occur outside of the anal verge (the distal end of the anal canal). They are sometimes painful, and can be accompanied by swelling and irritation. Itching, although often thought to be a symptom from external hemorrhoids, is more commonly due to skin irritation. \n\nIf the vein ruptures and a blood clot develops, the hemorrhoid becomes a thrombosed hemorrhoid. \n\nInternal hemorrhoids are those that occur inside the rectum. As this area lacks pain receptors, internal hemorrhoids are usually not painful and most people are not aware that they have them. Internal hemorrhoids, however, may bleed when irritated. \n\nUntreated internal hemorrhoids can lead to two severe forms of hemorrhoids: prolapsed and strangulated hemorrhoids. \n\nProlapsed hemorrhoids are internal hemorrhoids that are so distended that they are pushed outside of the anus. \n\nIf the anal sphincter muscle goes into spasm and traps a prolapsed hemorrhoid outside of the anal opening, the supply of blood is cut off, and the hemorrhoid becomes a strangulated hemorrhoid.

Hemorrhoids are actually varices around the anus. The rectum is further up and Preparation H is not used for the rectum. Also, if the bleeding is actually rectal, it is not a hemorrhoid and is probably something more serious.
