What type of laxative is recommended for severe constipation?

Stimulant laxatives are the recommended choice for severe constipation because they work by directly stimulating the intestines to promote a bowel movement. This increased peristalsis is particularly effective for individuals who have not responded to other laxatives or have significant constipation. Stimulant laxatives, such as bisacodyl and senna, can facilitate faster bowel evacuation, which is important in cases where immediate relief is necessary.

Osmotic agents and bulk-forming laxatives are often used for less severe cases of constipation. Osmotic agents, such as polyethylene glycol, draw water into the intestines to soften the stool and increase stool frequency, whereas bulk-forming laxatives, such as psyllium, increase stool bulk and promote normal bowel movements over time. However, in severe cases, the rapid action provided by stimulant laxatives is usually preferred.

Antispasmodics are not laxatives at all; they are used to relieve smooth muscle spasms in the gastrointestinal tract and do not directly address constipation. Thus, they are not appropriate for treating severe constipation specifically.
