Diarrhea: This is characterized by rapid movement of fecal contents through the large intestine, resulting in liquid stools. Ignoring the urge to defecate has the opposite effect - it slows transit time.

Incontinence: Fecal incontinence is the involuntary loss of bowel control. While chronic constipation can eventually lead to overflow incontinence (where liquid stool leaks around a hard mass), the direct, immediate result of ignoring the urge is the retention of stool, not the loss of control.

Hemorrhoids: While hemorrhoids are often a secondary result of constipation (due to straining to pass hard stool), the physiological process initiated by ignoring the urge is the hardening of stool, which is the definition of constipation. Constipation is the direct result; hemorrhoids are a potential complication of that result.

Large quantities of fat mixed with pale yellow liquid stool: This describes steatorrhea, which is associated with malabsorption syndromes like celiac disease or cystic fibrosis or gallbladder or pancreatic issues, but not typically active bleeding.

Brown, formed stools: This is the description of normal, healthy stool. The brown color comes from stercobilin, a bile derivative, and indicates no significant bleeding in the tract.

Narrow, pencil-shaped stool: Pencil-shaped stools are a red flag for a physical obstruction in the lower colon or rectum, such as a tumor or stricture, but they do not specifically validate active bleeding.

Anticoagulants cause a white discoloration of the stool: Anticoagulants like warfarin or heparin increase the risk of GI bleeding, which would cause the stool to appear pink, red, or tarry. White or clay-colored stools are caused by antacids or a lack of bile (biliary obstruction).

Narcotic analgesics increase gastrointestinal motility: Opioids/narcotics are notorious for decreasing motility by binding to receptors in the gut, leading to significant constipation.

Iron salts impair digestion and cause a green stool: While iron can cause GI upset, it characteristically causes the stool to turn black and tarry (which can be mistaken for melena) and often causes constipation.

Meat: Protein-rich foods like meat are generally digested in the stomach and small intestine and are not primary triggers for gas, although they can contribute to the odor of gas due to sulfur content.

Potatoes: While potatoes contain starch, they are generally considered gas-friendly compared to other carbohydrates. Most of the starch in potatoes is digested easily, leaving little for the gas-producing bacteria in the colon.

Ice cream: While dairy can cause gas in individuals with lactose intolerance, it is not a universal gas-producer for the general population in the same way that high-fiber cruciferous vegetables are.
