Fecal Incontinence: Causes and Regenerative Treatments

At IMAGE REGENERATIVE, we support people every day who live with fecal incontinence, a delicate condition that profoundly affects quality of life, relationships, and daily well-being.

Within our regenerative colonproctology with Lipogems® pathway, we combine specialist proctological surgery with regenerative medicine based on autologous micro-fragmented adipose tissue, rich in mesenchymal cells, developed by Professor Carlo Tremolada.

Our goal is to treat anal sphincter weakness by addressing the root cause of the problem, helping patients naturally regain bowel control through minimally invasive means. In this guide, we examine what fecal incontinence is, its symptoms and causes, and how regenerative treatments offer a different perspective compared to conventional remedies.

What is fecal incontinence and what are the symptoms

Fecal incontinence is the involuntary loss of stool, liquid or solid, and in some cases gas, due to reduced ability to control defecation. It is a more widespread condition than commonly thought, often experienced with embarrassment and therefore reported to doctors with considerable delay.

Symptoms present in different forms. In urge incontinence, the person feels a sudden and urgent stimulus and cannot reach the bathroom in time. In passive incontinence, leakage occurs without perceiving any warning, sometimes associated with small amounts of mucus or underwear soiling. These disturbances are often accompanied by a sensation of incomplete emptying and progressive loss of confidence in activities outside the home. The resulting psychological distress leads many people to reduce their social life, which is why timely assessment is as important as the therapy itself.

Causes of fecal incontinence: from obstetric trauma to aging

The causes of fecal incontinence are often multiple and tend to accumulate over time. Among the most frequent in women are obstetric traumas: natural childbirth, particularly when accompanied by perineal tears or episiotomy, can damage the sphincter muscles and pelvic floor nerves, with effects that sometimes manifest only years later.

Scar tissue from previous perianal surgeries can also, in some cases, affect sphincter integrity. With advancing age, muscles lose tone and rectal sensitivity decreases, favoring the onset of the disorder. Neurological conditions such as diabetes, multiple sclerosis, stroke sequelae or spinal cord injuries, chronic diarrhea related to inflammatory bowel diseases, rectal prolapse, and pudendal nerve neuropathy also contribute. Recognizing the predominant factor is the first step in establishing targeted treatment.

Fecal incontinence in the elderly: why it is more frequent

In the elderly population, fecal incontinence becomes more common due to a combination of factors. Sarcopenia, the progressive loss of muscle mass and strength, also affects the anal sphincters and reduces the ability to retain stool. This is compounded by weaker sphincter tone, reduced rectal sensitivity, and decreased tissue elasticity.

The situation becomes more complex when reduced mobility, which makes it harder to reach the bathroom in time, any cognitive deficits, and the use of medications that alter stool consistency come into play. In the elderly, the effects of past childbirths and surgeries also tend to accumulate. For this reason, evaluating elderly patients requires a comprehensive perspective, capable of considering overall frailty and aiming to realistically improve continence and daily independence.

Diagnosis and the role of colonproctology

Accurate diagnosis is the foundation of any effective treatment, and colonproctology plays a central role in this. The process begins with a detailed medical history and physical examination, which includes rectal examination to assess sphincter tone and strength.

For further investigation, the specialist uses targeted instrumental examinations. Anorectal manometry measures pressure and sphincter muscle competence, while endoanal ultrasound allows precise visualization of any lesions or sphincter interruptions. In selected cases, videodefecography, which analyzes evacuation dynamics, and electromyography to study muscular activity are used. When needed, the assessment is completed with a colonoscopy. At IMAGE REGENERATIVE, this evaluation is coordinated by Dr. Alberto Giori, among the first in Italy to apply regenerative therapy to proctological surgery, translating diagnostic data into a personalized treatment plan.

Traditional remedies and treatments for fecal incontinence

Traditional treatments for fecal incontinence generally follow a gradual approach. In mild forms, lifestyle and dietary interventions are implemented, increasing fiber intake to regulate bowel movements, and antidiarrheal medications are used to make stools more compact. An important role is assigned to pelvic floor rehabilitation with biofeedback techniques, which help strengthen and coordinate the muscles.

In more challenging cases, sacral neuromodulation, injection of bulking agents, and, when indicated, surgical sphincteroplasty to repair the damaged sphincter are considered. In severe situations, colostomy may be necessary.

While these remedies offer concrete benefits, they may have long-term limitations related to progressive weakening of repaired tissues or depletion of bulking substance effects.

Starting from these limitations, at IMAGE REGENERATIVE we have chosen to complement classical techniques with the regenerative approach, which aims to rebuild sphincter tissue quality instead of merely managing its consequences.

Regenerative treatments: how treatment with Lipogems® works

Regenerative treatments represent one of the most promising directions in modern colonproctology, and Lipogems® is a concrete example. The technique uses the patient's own adipose tissue, harvested through a small aspiration from the abdomen under local anesthesia.

The tissue is then micro-fragmented through a closed system, without chemical manipulation, to obtain a concentrate rich in mesenchymal stem cells, growth factors, and components that support repair.

This concentrate is infiltrated into the anal sphincter muscles, where the cells exert an anti-inflammatory action and stimulate regenerative processes in weakened or scarred tissues. The entire procedure takes on average 60 to 90 minutes and is performed on an outpatient basis, with generally rapid return to daily activities.

An initial pilot study conducted by the IMAGE REGENERATIVE team and published in 2015 followed the first five patients treated with this method for two years, observing significant improvement in continence and pain reduction. These are encouraging results that must nevertheless be evaluated on a case-by-case basis.

Lipogems® for sphincter regeneration: benefits and recovery

The main value of the Lipogems® approach for sphincter regeneration lies in acting directly on muscle tissue quality, going beyond simple momentary symptom control. Being autologous tissue, the risk of rejection reactions is very limited, and the minimally invasive nature of the procedure makes it suitable even for those who prefer to avoid more aggressive interventions.

The infiltration can help strengthen the sphincter muscles, reduce pain, and gradually improve the ability to retain stool. It is important to emphasize that results may vary from person to person depending on the baseline clinical condition.

Recovery is generally smooth. After the procedure, a period of attention to diet and local hygiene is recommended, with scheduled follow-ups at one, three, six, and twelve months to monitor progression. In many cases, the pathway is integrated with perineal physiotherapy exercises to optimize function.

The treatment is available at IMAGE REGENERATIVE locations in Milano and St. Moritz, where each treatment plan is defined after a specialist evaluation, because choosing the most appropriate therapy always depends on the cause and degree of incontinence.

Frequently asked questions

Can fecal incontinence be cured?

Fecal incontinence can be treated and, in many cases, significantly improved. The outcome depends on the cause and severity of the disorder. Options range from pelvic floor rehabilitation to regenerative therapies like Lipogems®, which act on sphincter tissue weakness. An accurate colonproctological evaluation allows identification of the most appropriate pathway for each person.

Who should you consult for fecal incontinence?

The reference specialist is the colonproctologist, a physician expert in anorectal and pelvic floor conditions. Through clinical examination and investigations such as anorectal manometry and endoanal ultrasound, they identify the cause of the disorder and propose the most appropriate therapy, from conservative options to regenerative solutions.

How does Lipogems® treatment for the anal sphincter work?

The treatment involves harvesting a small amount of adipose tissue from the abdomen, its micro-fragmentation with a closed system, and infiltration of the concentrate rich in mesenchymal stem cells into the sphincter muscles. The cells perform an anti-inflammatory and regenerative action aimed at strengthening tissues and improving continence.

How long does the Lipogems® procedure and recovery take?

The procedure takes on average 60 to 90 minutes and is performed under local anesthesia on an outpatient basis. Recovery of normal activities is usually rapid. Follow-ups are scheduled at one, three, six, and twelve months, often combined with perineal physiotherapy exercises to support long-term results.
