How long does a hemorrhoid flare-up last?

Pain that appears without warning, often after a heavy meal, an episode of constipation, or a long day of sitting. This is called an hemorrhoidal flare-up. And the first question is: how long will it last?

It varies greatly from person to person, but certain benchmarks can help you get your bearings.

What an Hemorrhoidal Flare-up Really Is

A flare-up is a sudden inflammatory surge in already weakened hemorrhoids. The hemorrhoidal veins swell, local blood circulation slows down, and pain sets in, sometimes very intensely. In some cases, a clot forms inside a vein: this is hemorrhoidal thrombosis, the most painful form.

Approximately one in two French people experiences at least one hemorrhoidal flare-up per year, according to SNFCP data. The discomfort affects both men and women, especially between the ages of 30 and 50.

Duration Depending on the Type of Flare-up

A simple flare-up, without thrombosis, generally lasts from a few days to a week. This is the acute phase: pain, itching, sometimes bleeding. With appropriate treatment, venotonics, analgesics, and dietary adjustments, symptoms improve in less than a week for most people.

Hemorrhoidal thrombosis follows a different timeline. The most intense pain lasts four to seven days. The associated edema resolves in three to four days. But the clot itself can persist for two to six weeks. The total discomfort can therefore last several weeks even if the worst is quickly over.

Without any treatment, some people report discomfort that lasts one to two months. This is not the norm, but it is possible when the trigger factors are not corrected.

Factors That Prolong a Flare-up

Constipation is the main culprit. When stools are hard and straining efforts are repeated, the pressure on the hemorrhoidal veins does not decrease between flare-ups. Inflammation is maintained. The same applies to prolonged sitting, a diet low in fiber, or low water consumption.

Strong spices, alcohol, and very fatty foods are known triggers, not systematically, but frequently. Episodes of intense stress or repeated diarrhea can also precipitate a flare-up in predisposed individuals.

Why Flare-ups Return

The real problem with hemorrhoids is not the flare-up itself. It's what happens between flare-ups. The venous tissue does not fully recover its tone without long-term treatment. It remains slightly distended, more vulnerable to the next surge. This is why many people describe increasingly frequent flare-ups over time.

Conventional treatments, creams, suppositories, calm the symptoms but do not act on this underlying mechanism. Restoring venous tone, which involves active ingredients such as escin or ruscogenins, makes the difference between calming a flare-up and preventing subsequent ones.

When a Flare-up Becomes an Emergency

Most hemorrhoidal flare-ups are painful but not dangerous. Some situations require a quick consultation: very intense pain with sudden onset, a large thrombosis, abundant and repeated bleeding, associated fever, or the inability to relieve pain with usual analgesics.
