How do skin tags develop?
Skin tags usually develop due to overstretching or damage to the sensitive skin in the anal area. Common causes include mechanical stress such as straining during bowel movements, persistent constipation, or recurring diarrhea. A previous anal vein thrombosis, but especially recurring anal vein thromboses can leave skin tags when the blood clot has been broken down but excess skin remains. Pregnancy and childbirth also promote the formation of skin tags, as the increased pressure on the anal region can weaken the connective tissue. Inflammatory processes, such as those occurring with hemorrhoids or chronic inflammatory bowel diseases, can also contribute to their development. Additionally, a genetic predisposition for weak connective tissue can increase the risk of skin tags. While skin tags themselves are harmless, they can cause symptoms such as itching, swelling, or bleeding due to friction, poor hygiene, or mechanical irritation.

Are skin tags a consequence of hemorrhoids?
Yes, skin tags can develop as a result of hemorrhoids. When hemorrhoids swell and then shrink, the overstretched skin may not always fully return to its original state. This can leave skin flaps at the anal margin. Especially after an inflamed or thrombosed hemorrhoid, excess skin can form that remains as a skin tag. Even after hemorrhoid treatment, such as rubber band ligation or sclerosis, the skin can shrink, leaving skin tags behind. While hemorrhoids often cause symptoms like pain or bleeding, skin tags are usually harmless. However, skin tags can make anal hygiene more difficult and, through friction or moisture, lead to itching or irritations as well as swelling. Anyone unsure whether a skin change is due to hemorrhoids or skin tags should consider a proctological examination. Skin tags can also occur without previous hemorrhoids. They arise from various factors that stretch or irritate the skin in the anal area. Common causes include:
Strong straining during bowel movements: Chronic constipation or repeated straining can stress the anal skin and lead to the formation of skin tags.
Diarrhea or frequent irritations: Repeated inflammations or irritations from frequent, loose stools can overstretch the skin.
Pregnancy and childbirth: Hormonal changes and pressure during childbirth can stretch the anal skin and promote the formation of skin tags.
Anal thrombosis: An anal thrombosis is a swelling caused by a blood clot at the anus that can leave a skin tag after healing.
Mechanical irritations: Tight clothing, excessive wiping, or moist skin promote the formation of skin folds.
With or without hemorrhoids – skin tags are usually harmless but can make hygiene difficult or cause irritation.
Can strong straining during bowel movements cause skin tags?
Yes, strong straining during bowel movements can cause skin tags. Excessive straining stretches and stresses the sensitive skin in the anal area, which can lead to micro-injuries or overstretching of the tissue. These skin changes can appear as skin tags after healing.
Skin tags most often develop due to chronic constipation, as hard stool and strong straining overstress the anal skin. Repeated strong straining after diarrhea can also irritate the skin and promote the formation of skin tags.
To minimize the risk, a fiber-rich diet with sufficient fluids should be observed. Psyllium husks or flaxseeds can help regulate bowel movements. Also, strong straining should be avoided to protect the skin in the anal area.

Do diarrhea or constipation promote the formation of skin tags?
Yes, both diarrhea and constipation can promote the formation of skin tags, as they put a lot of strain on the skin in the anal area.
Diarrhea: Frequent, loose stool leads to increased wiping, which irritates the sensitive anal skin. Additionally, constant moisture can soften the tissue and make it more prone to skin changes. Chronic diarrhea can also promote inflammation in the anal area, contributing to the formation of skin tags.
Constipation: Hard stool and straining during bowel movements put high pressure on the anal skin. This can cause small injuries or overstretching, which remain as skin tags after healing.
Prevention: A diet rich in fiber, sufficient fluids (at least 1.5–2 liters daily), and gentle anal hygiene can help minimize the risk of skin tags.
Why do skin tags develop after an anal thrombosis?
Skin tags develop after an anal thrombosis as a result of the natural healing of the affected tissue. An anal thrombosis is a painful blood clot formation in the external anal veins, often accompanied by swelling and tenderness. After the blood clot breaks down, excess skin often remains that does not fully retract – these remaining skin flaps are called skin tags.
Why do skin tags remain after an anal thrombosis?
Overstretching of the anal skin: The severe swelling caused by the blood clot stretches the tissue, and after it subsides, excess skin often remains.
Loss of skin elasticity: The skin may not always fully retract after stretching, especially if elasticity is impaired by repeated thromboses or inflammations.
Inflammatory processes: During healing, small scars may form that change the skin structure and contribute to the development of skin tags.
Prevention: Gentle anal hygiene, avoiding straining during bowel movements, and a high-fiber diet can help prevent anal thrombosis and associated skin tags.

What role do pregnancy and childbirth play in the development of skin tags?
Pregnancy and childbirth are common factors in the development of skin tags, as they increase pressure on the anal region and affect blood flow in the pelvic area.
Why do skin tags develop during pregnancy?
Increased pressure in the abdominal cavity: During pregnancy, the pressure on the pelvic organs increases, which can strain the veins in the anal area. This can lead to an expansion of the blood vessels, promoting the formation of skin tags.
Hormonal changes: Pregnancy hormones, especially progesterone, lead to a softening of connective tissue and dilation of veins, increasing the risk of excess skin after inflammations.
Constipation: Many pregnant women suffer from constipation due to hormonal influences and limited movement, which promotes strong pushing – a risk factor for marisks.
How does childbirth affect the development of marisks?
Strong pushing during delivery: During childbirth, pushing causes extreme strain on the pelvic floor and anal region. This can cause small skin tears or venous congestion, which after healing appear as marisks.
Hemorrhoids as a precursor: Many women develop hemorrhoids during or after childbirth, which can leave excess skin after they subside or regress.
Prevention: A fiber-rich diet, sufficient fluid intake, regular gentle exercise, and mindful bowel habits can help prevent marisks during pregnancy and after childbirth.
Are marisks caused by poor hygiene?
Marisks do not arise directly from poor hygiene but are usually the result of mechanical stress, connective tissue weakness, or venous congestion in the anal area. Nevertheless, insufficient or aggressive anal hygiene can irritate existing marisks and worsen the symptoms of marisks such as itching, inflammation, or swelling.
Why is hygiene important with marisks?
Remaining stool residues: Since marisks form skin folds around the anus, stool residues can accumulate more easily. Insufficient cleaning can promote skin irritation and inflammation.
Too aggressive cleaning: Rubbing hard with toilet paper, using alcohol-based wet wipes, or aggressive soaps can irritate the sensitive skin and cause small cracks.
Moisture in the skin folds: Remaining moisture after cleaning can create a damp-warm environment that promotes the growth of bacteria or fungi, which in turn causes itching and irritation.
Optimal hygiene for the prevention and care of marisks
-
Gentle cleaning with lukewarm water instead of soap or perfumed wet wipes.
-
Soft toilet paper or cleaning with a bidet instead of vigorous wiping.
-
Thorough drying by gentle patting or using a hairdryer on a low setting.
-
Moisturizing and soothing care with ointments such as witch hazel or calendula ointment.
Poor hygiene does not cause skin tags, but it can worsen the symptoms of skin tags. Gentle but thorough anal hygiene helps to avoid irritation and inflammation. Learn more here about the treatment of skin tags, or approaches within the framework of alternative therapy for skin tags.
Can inflammatory bowel diseases cause skin tags?
Yes, inflammatory bowel diseases (IBD) such as Crohn's disease and ulcerative colitis can promote the development of skin tags. These diseases are associated with chronic inflammation and changes in the intestinal and anal area that weaken the tissue and promote the formation of skin flaps at the anus.
Why do inflammatory bowel diseases promote skin tags?
Chronic inflammation: The persistent inflammation in the intestine can spread to the anal area, making the tissue more susceptible to changes.
Swelling and circulatory disorders: Inflammatory processes can impair blood circulation in the anal area and lead to the formation of excess skin tissue.
Frequent diarrhea: Recurring, often aggressive stools in Crohn's disease or ulcerative colitis can irritate the skin and increase the risk of mMechanical stress and scar formation increase.
Perianal fistulas and abscesses: Patients with Crohn's disease more frequently have perianal fistulas, anal abscesses, or anal thromboses, which can lead to skin tags after healing.
How can marisks be prevented in IBD patients?
Inflammation control: Good therapy of the underlying disease reduces the risk of anal changes.
Gentle hygiene: Lukewarm water and soft toilet paper avoid irritation.
Sitz baths: Chamomile or oak bark baths soothe inflamed tissue.
Diet adjustment: An individually tolerable diet helps to avoid aggressive diarrhea.
Marisks are not uncommon in patients with inflammatory bowel diseases. Optimal treatment of the underlying disease and gentle anal hygiene can help minimize the risk.
Are there genetic causes for marisks?
Marisks themselves are not a classic hereditary disease, but a genetic predisposition can indirectly increase the risk of their development.
How can genetics influence marisks?
Connective tissue weakness: A genetic predisposition to weak or less elastic connective tissue can make the skin more susceptible to changes, especially in the anal area.
Predisposition to hemorrhoids or anal vein thrombosis: People with a family tendency to hemorrhoids or anal vein thrombosis have a higher risk of marisks, as these often develop as a consequence of such diseases.
tendency to chronic bowel diseases: Genetically caused inflammatory bowel diseases such as Crohn's Disease or Ulcerative colitis can indirectly promote marisks through chronic irritation in the anal area.
metabolic and circulatory problems: Hereditary factors such as venous diseases or impaired circulation can weaken the tissue in the anal area and increase the risk of skin changes.
While marisks are not directly inherited, genetic factors such as connective tissue weakness or a family tendency to hemorrhoids and circulatory disorders can increase the risk. Those with a family history can reduce the risk of marisks through healthy digestion, gentle anal hygiene, and avoiding strong straining during bowel movements.

What factors promote the new formation of skin tags?
Skin tags can reoccur after their initial formation, especially if certain risk factors are present. These involve mechanical irritation, digestive problems, and skin changes in the anal area.
Mechanical stress and irritation
Strong straining during bowel movements: Excessive pressure on the sensitive tissue can cause skin protrusions again.
Frequent friction: Tight clothing or vigorous wiping with dry toilet paper irritate the skin and promote the formation of new skin tags.
Sports with high pressure load: Strength training, heavy lifting, or prolonged sitting (e.g., cycling) can strain the anal area and promote new skin tags.
Digestive problems and stool habits
Chronic constipation: Hard stools and repeated straining put stress on the tissue.
Frequent diarrhea: Constant irritation from liquid stool can weaken the skin in the anal area.
Unbalanced diet: A low-fiber diet leads to digestive problems that promote mechanical stress.
Skin and vascular factors
Hemorrhoids or anal thromboses: Existing vascular changes or their regression can lead to new skin tags.
Weak connective tissue: Genetic predisposition can contribute to tissue loosening more quickly.
Pregnancy and childbirth: Pressure on the anal area during pregnancy or straining can lead to new skin tags.
Hygiene and skin care
Insufficient anal hygiene: Remaining stool residues in the skin folds can lead to irritation.
Excessive cleaning: Strong rubbing, aggressive soaps, or alcohol-based wet wipes dry out the skin and promote irritation.
