Saggy Mons Pubis: Causes of Mons Ptosis and How It Is Treated

A saggy mons pubis is a common change, especially after weight loss or pregnancy, but it is rarely talked about. The mons pubis is the rounded mound of skin and fat over the pubic bone. When it drops, it can hang lower than before, bulge in clothes, rub, and make hygiene and sex less comfortable. Doctors call this mons ptosis. This guide explains what causes it, how to tell it apart from fat, and the treatment options available in the UK.

If you want the background on how this area is built and why fat collects there, read our guide to mons pubis fat first.

This guide is general information, not medical advice. If you notice a new lump, swelling, pain, a rash that will not settle or any change you are worried about, speak to your GP.

Key Takeaways

• Mons ptosis means the skin and fat of the mons pubis have dropped, usually because the skin has stretched and lost its support.
• The most common causes are major weight loss, pregnancy and ageing.
• Fat loss can shrink a full mons, but it cannot lift or tighten loose skin.
• Monsplasty, also called a mons lift or pubic lift, is the main treatment and is often combined with a tummy tuck.
• Surgery for appearance is not usually available on the NHS, so most people in the UK pay privately.

What Is Mons Ptosis?

The mons pubis and how it is held in place

The mons pubis is a pad of fat covered by skin that sits in front of the pubic bone. Fibrous bands under the skin help hold it in place against the lower tummy wall. When the skin stretches and these supports loosen, the mons slides downwards. This is what doctors mean by ptosis, which simply means drooping.

Sagging versus a bulging mons pubis

A bulging mons pubis sticks forward because of a thick layer of fat. A saggy mons pubis hangs downwards because of loose skin. Many people have a mix of both. The difference matters, because fat and loose skin are treated in different ways.

How surgeons grade it

Plastic surgeons usually describe mons ptosis by how far the mons has dropped and how much fat it contains. In mild cases the area is full but sits close to its normal position. In more advanced cases the skin hangs over the top of the genitals, sometimes under an overhanging lower belly. The grade helps a surgeon decide whether liposuction, a lift or both will give the best result.

What Causes a Saggy Mons Pubis?

Mons pubis after weight loss

Major weight loss is the most common cause. When the body stores a lot of fat, the skin over the mons stretches to cover it. After weight loss, whether from diet, weight loss injections or bariatric surgery, the fat shrinks but the skin often does not shrink back fully. The result is an empty, loose mons that hangs lower than before. Our guide to the FUPA after weight loss covers the wider changes to the lower belly.

Pregnancy

Pregnancy stretches the skin of the lower belly and the mons, and the extra weight presses down on the area. Several pregnancies or a large baby can make this more likely. A caesarean scar can also change how the tissue above the pubic bone sits.

Ageing and skin quality

Skin loses collagen and elastic fibres with age, so it becomes thinner and less springy. Gravity then has more effect. Sun damage, smoking and genetics can all affect skin quality as well.

A lower belly overhang

When the lower belly hangs forward, it can pull the mons downwards or press it from above. In this case, lifting the mons on its own may not be enough, and the belly also needs treating.

Fat or Loose Skin? How to Tell

The pinch test

Gently pinch the skin of the mons. If you can hold a thick, soft roll, a large part of the fullness is fat. If the skin feels thin and you can pull it away easily with little underneath, the main issue is loose skin. Our comparison of loose skin vs fat on the lower belly explains this check in more detail.

How the area changes with your weight

Fat grows and shrinks as your weight changes. Loose skin does not. If you have lost a lot of weight and the mons still hangs, the cause is mostly skin. If the area has grown with weight gain, fat is likely to be the bigger part.

Questions a surgeon will ask

A surgeon will want to know how much weight you have lost, whether your weight is stable, whether you plan more pregnancies, and what problems the area causes you day to day. They will also check the lower belly, as the two areas are often treated together.

Problems a Sagging Pubic Area Can Cause

Comfort and hygiene

Loose skin can create folds where sweat and moisture collect. This can lead to chafing, rashes and skin infections. Some people find it harder to keep the area clean.

Clothing

A low hanging mons can show as a bulge through tight trousers, leggings and swimwear, even when the rest of the body is slim.

Sex, peeing and confidence

In more advanced cases the skin can cover the genitals, which may make sex uncomfortable and, for some people, affect the direction of urine flow. Many people also feel self conscious about the area. A study of 23 women who had a monsplasty after massive weight loss found self esteem scores improved after surgery, and all patients were satisfied with the effect on hygiene, clothing and daily activities.

Can You Fix a Saggy Mons Pubis Without Surgery?

Reach a stable weight first

If the mons is still full of fat, steady weight loss will make it smaller and may make the sagging look less obvious. Surgeons usually advise getting to a weight you can keep before any operation, because big changes afterwards can affect the result.

Skin tightening treatments

Radiofrequency and similar energy devices aim to tighten skin by heating the deeper layers. They may help mild laxity, but results are modest and several sessions are often needed. They do not remove hanging skin. Our guide to non surgical FUPA removal compares these options.

Everyday support

High waisted, supportive underwear can hold the area in place and reduce rubbing. Wash and dry any skin folds every day, and use a barrier cream if you get chafing.

How Mons Ptosis Is Treated With Surgery

Monsplasty or mons lift

A monsplasty removes excess skin and some fat, then lifts the mons and fixes it to the firmer tissue above so it sits higher and flatter. The scar is usually placed low across the lower belly, where underwear can cover it. Read our full guide to monsplasty for how the operation works.

Liposuction

Liposuction removes fat through small cuts using a thin tube. It suits a full mons with good skin tone, but it does not lift a sagging mons and can make loose skin look worse if there is not enough fat to support it. See our guide to FUPA liposuction.

Combined with a tummy tuck

Mons ptosis is often treated at the same time as a tummy tuck, especially after weight loss. If the belly is tightened without lifting the mons, the mons can look even lower afterwards, so many surgeons assess both areas together. Our guide to a tummy tuck for a FUPA explains when the two are combined.

Comparing the options

Recovery, Risks and Cost in the UK

What recovery involves

Most people wear a compression garment for several weeks and avoid heavy lifting and hard exercise while the area heals. Swelling of the mons is common and can take weeks or months to settle fully. Your surgeon will give you a plan for returning to work and exercise.

Possible risks

Risks include bleeding, infection, fluid collecting under the skin, slow wound healing, numbness, a visible or raised scar, and the mons sitting higher or lower than you hoped. Smoking and a higher BMI raise the risk of problems. Our page on FUPA surgery risks covers these in more depth.

NHS or private?

The NHS explains that cosmetic surgery is not usually available on the NHS. Surgery after weight loss may sometimes be funded where loose skin causes medical problems, but criteria vary by area. Most people pay privately. See our guide to FUPA surgery cost for typical UK prices and how to choose a surgeon on the GMC specialist register.

Frequently Asked Questions

What causes a saggy mons pubis?

The main causes are major weight loss, pregnancy and ageing. Each stretches or weakens the skin and the tissue that holds the mons in place, so it drops lower.

Can exercise lift a sagging pubic area?

No. Exercise can help you lose fat and strengthen the tummy muscles, but it cannot tighten stretched skin or lift the mons back into place.

Will losing weight make mons ptosis worse?

It can make sagging more visible if the skin does not shrink back as the fat goes. That is why many people choose to reach a stable weight first and then consider a lift.

What is the surgery for a saggy mons pubis called?

It is called a monsplasty, mons lift or pubic lift. It is often carried out together with a tummy tuck.

Can I get a mons lift on the NHS?

Not usually for cosmetic reasons. In some areas, surgery to remove excess skin after weight loss may be funded if it causes medical problems. Ask your GP about local criteria.

The Bottom Line

Loose skin needs a different plan to fat

A saggy mons pubis is usually caused by stretched skin after weight loss, pregnancy or ageing. Fat loss can make a full mons smaller, but it will not lift loose skin. Skin tightening may help mild cases, liposuction suits extra fat with good skin, and a monsplasty is the main treatment for true mons ptosis, often alongside a tummy tuck. Reach a stable weight first, talk to a qualified surgeon, and see your GP about any new lump, pain or swelling. For more on this area, read our guide to mons pubis fat.
