The causes of hemorrhoids include genetic predisposition (weak rectal vein walls and/or valves), straining during bowel movements, and too much pressure on the rectal veins due to poor muscle tone or poor posture. Hemorrhoids may also result from portal hypertension because of the portacaval anastomoses. Anal sex can also stress the anus particularly if too little lubricant is used (vaginal sex is self lubricating) and cause rectal wall strain. Hemorrhoids are also linked to sitting for prolonged periods of time.[citation needed]Mayo Clinic - Causes of Hemorrhoids
Additional factors that can influence the course of hemorrhoids (mostly by increasing rectal vein pressure), especially for those with a genetic predisposition, are obesity and a sedentary lifestyle.
Constipation, chronic diarrhea, poor bathroom habits, pregnancy, postponing bowel movements, and fiber-deprived diet may be associated with bowel movement and straining, but not all of these have been conclusively proved to cause hemorrhoids.
Squatting
Using a squat toilet has been hypothesised to reduce straining and therefore reduce the occurrence of hemorrhoids. However, the medical research into this subject is scarce, and there has been no definite proof for this hypothesis. Hemorrhoids are very rare in nations where people squat to defecate , but this epidemiological argument doesn't necessarily prove a causal relationship.
Food
Dehydration can cause a hard stool or chronic constipation which can lead to hemorrhoidal irritation. An excess of lactic acid in the stool, a product of excessive consumption of milk products such as cheese, can cause irritation and a reduction of consumption can bring relief. Vitamin E deficiency is also a common cause.
Excessive alcohol or caffeine consumption can cause diarrhea which in turn can cause hemorrhoidal irritation.
Food considered "probiotic," such as yogurt with active culture, may help keep the gut functioning normally and thus help prevent flare-ups.
