Neck hump: fat pad, curved spine or normal bone? Causes and what helps

A "neck hump" can mean different things: a soft pad of fat over the base of the neck (often called a buffalo hump), a more rounded upper back (sometimes called a dowager's hump), the normal bony bump of a vertebra that everyone has, or a fatty lump called a lipoma. They have different causes and need different things.

Exercise can't melt a fat pad, and chin tucks won't remove one. A fat pad can go with overweight, and sometimes with steroid medicines or Cushing's syndrome, which need a GP. A rounded upper back responds a little to back-strengthening. This guide explains the differences, what exercise can and can't change, and when to get checked.

The short version

Several things share the name

A neck hump can be a soft fat pad over the base of the neck, a rounded upper back, the normal bony bump of a vertebra, or a lipoma (a soft, harmless fatty lump). A GP can usually tell which it is, and can arrange a scan if there's doubt.

Fat pads go with weight and some medicines

A fatty hump can go with overweight and metabolic problems, and with Cushing's syndrome, which is most often caused by taking high-dose steroid medicine for a long time. Older HIV medicines also caused fatty humps.

Sources 5, 6, 7

Exercise doesn't spot-remove fat

Most trials found exercising one area didn't remove fat from it; one small trial found a little. We found no study that tested exercise for a neck fat pad, and chin tucks don't melt it.

Sources 8, 9, 10

A curve-type hump changes a little

If the hump is a rounded upper back, back-strengthening reduced the curve by about 3 degrees in a 6-month trial, and a review of 24 studies found a small benefit. The kyphosis guide covers it.

Sources 11, 12

When to see a GP

See a GP for a lump that's growing, hard, painful, red or hot; for a hump with a round red face, thin arms and legs, easy bruising or stretch marks, especially if you take steroids; or for a newly rounded back with pain or height loss. Never stop steroid medicine on your own.

Sources 4, 6, 13, 14, 15

Removal is possible

A fatty hump can be removed by liposuction or surgery; in low-quality studies it came back after liposuction in about 1 in 10. The NHS usually removes a lipoma only if it's growing or causing problems.

Four things a neck hump can be

A fat pad (buffalo hump)

A soft pad of fat over the base of the neck and the top of the back, called a dorsocervical fat pad. In 383 people who had surgery for a buffalo hump, about 78% had a fat pad, 11% a more general build-up of fat and 10% a lipoma; only one had HIV.

Source 1

A rounded upper back (dowager's hump)

"Dowager's hump" is an old name for a rounded upper back in later life (age-related hyperkyphosis), which can come from disc wear, weaker back muscles or spinal fractures. The kyphosis guide covers it in detail.

Source 2

The normal bony bump

Everyone has a bony bump at the base of the neck: the back of a vertebra. Textbooks name the seventh neck vertebra (C7) as the most prominent, but in 39 bodies studied after death it was C7 in about half, C6 in about a third and C5 in about 1 in 10.

Source 3

A lipoma

A lipoma is a soft, fatty lump that grows under the skin. Lipomas are common and harmless, are often found on the shoulders or back, and may move slightly when you press them.

What the evidence says

Fat pads go with metabolic problemsEmerging evidence

In a small series of 12 people with a buffalo hump who didn't have HIV, the average body mass index was 30 (the threshold for obesity), and most had high blood pressure, diabetes or high cholesterol; three were newly diagnosed. The authors suggested checking for these conditions. The series is tiny, so treat it as a reason to ask, not as proof.

Sources 5, 1

Steroid medicine and Cushing's syndromeStrong evidence

Cushing's syndrome is caused by too much of the hormone cortisol, most often from taking high doses of steroid medicine, such as prednisolone, for a long time, and less often from a growth in the pituitary or adrenal gland.

It adds fat to the neck, upper back, chest and tummy, with thin arms and legs, a red, round face, easy bruising, stretch marks and weak muscles at the tops of the arms and legs. The NHS advises seeing a GP, particularly if you take steroid medicine, and not stopping steroids without talking to your doctor.

Sources 6, 13

Older HIV medicinesEmerging evidence

Older HIV medicines, especially stavudine and zidovudine, caused fat loss in some areas and fat gain in others, including fatty lumps. Switching to newer drugs reduced it, but it doesn't always go away. Modern HIV treatment is linked more to general weight gain.

Source 7

Exercise doesn't remove fat from one spotMixed evidence

In 24 adults, 6 weeks of abdominal exercise didn't reduce tummy fat. In 11 people, 12 weeks of training one leg reduced fat elsewhere in the body but not in that leg. One small trial in 16 men found trunk fat fell more when tummy exercises were added to running. We found no study that tested exercise for a neck fat pad.

Sources 8, 9, 10

A rounded upper back changes a littleEmerging evidence

In the SHEAF trial (Study of Hyperkyphosis, Exercise and Function), 6 months of back-strengthening and posture classes reduced the upper-back curve by 3 degrees on X-ray, and a review of 24 studies found a small benefit. Spinal bones that have fractured keep their compressed shape.

Sources 11, 12, 17

Chin tucks move the head, not fatEmerging evidence

Exercise programmes for forward head posture moved the head back by about 3 degrees in trials, and lying chin tucks improved how people hold their head. That changes head position, not the fat over the neck.

Sources 18, 19

What helps, by cause

A fatty hump: look for the cause

See a GP to check for Cushing's syndrome, especially if you take steroids; if steroids are the cause, treatment may include reducing them gradually under medical supervision. If you take HIV treatment, ask your HIV clinic about your medicines. If you're overweight, ask whether a check of your blood pressure, blood sugar and cholesterol makes sense.

Sources 6, 13, 7, 5

Losing fat overall

Because exercise doesn't target one spot, losing fat overall, through diet and activity, is the logical route for a fat pad. We found no study that measured the neck pad after weight loss, so this is our editorial reasoning. The exercise for weight loss guide covers what works.

Sources 8, 9

A rounded upper back: strengthen your back

Back-muscle exercises, such as the low cobra and the seated upper-back lift, at the UK osteoporosis consensus dose of 3 to 5 repetitions held 3 to 5 seconds, at least twice a week, building towards the SHEAF trial's 2 sets of 8 if you don't have osteoporosis. The kyphosis guide has the full routine.

Sources 20, 11

A forward head: chin tucks and upper-back strength

Lying chin tucks, up to 10 holds of up to 10 seconds once or twice a day at a light effort (our editorial starting point), with upper-back strength work. These change head position a little, not fat. The forward head posture guide has the details.

Sources 19, 21

If the hump is posture or a rounded back

These change posture a little; none removes fat. Chin tucks, 10 holds of 5 seconds, and lying chin tucks, up to 10 holds of 10 seconds (our editorial starting points); seated upper-back lifts and low cobras, 3 to 5 holds of 3 to 5 seconds, at least twice a week (UK osteoporosis consensus); Y-T-W raises, 5 to 8 of each letter, and wall angels, 8 slow slides (our editorial starting points).

Removing a fatty hump

Liposuction or surgeryMixed evidence

A fatty hump can be removed by liposuction or by cutting it out. In a review of 22 low-quality studies (218 patients, mostly with HIV), the hump came back in about 1 in 10 after liposuction, and fluid collections, bleeding under the skin and wound problems were more common after cutting it out.

In 383 people treated at one clinic, none came back, but 14% had numbness and 6% a fluid collection.

Lipomas on the NHSStrong evidence

Because lipomas are harmless, the NHS usually removes one only if it's growing or causing problems.

When to see a GP

A lump

See a GP about any new lump, and sooner if it's:

  • Growing.
  • Hard, and doesn't move when you press it.
  • Painful.
  • Red or hot.

Source 4

A hump with other changes

See a GP if a hump comes with a red, round face, thin arms and legs, easy bruising, stretch marks or weak muscles at the tops of your arms and legs, especially if you take steroid medicine. Don't stop or cut down steroids on your own: talk to your doctor first.

Sources 6, 13

A newly rounded back

A new or increasing hunch with back pain or height loss can be a spinal fracture from osteoporosis, and not every spinal fracture hurts. See a GP.

Myths

"Chin tucks get rid of a neck hump."Mixed evidence

They move the head back a few degrees; they don't remove a fat pad, and we found no study testing exercise for one.

Sources 18, 8, 9

"A neck hump is always fat."

It can be a fat pad, a lipoma, a rounded upper back or the normal bump of a vertebra.

Sources 1, 3, 2

"Looking at your phone gives you a neck hump."

We found no study linking phone use to a neck hump. Fat pads go with weight, metabolic problems, steroid medicine and older HIV medicines, and a rounded upper back mostly comes with age.

Sources 5, 6, 7, 2

"Only Cushing's syndrome causes a buffalo hump."

It's one cause, and it comes with other signs. Fat pads can also go with overweight and metabolic problems, and older HIV medicines caused them.

Sources 6, 5, 7

"A posture corrector will flatten a neck hump."Mixed evidence

Braces change your position while you wear them, and we found no study showing a lasting change. They can't remove fat.

Sources 23, 24

Questions people ask

What causes a neck hump?

It can be a pad of fat over the base of the neck, a more rounded upper back, or the bony bump of a vertebra that everyone has. Less often it's a fatty lump called a lipoma. A fat pad can go with overweight, with long-term steroid medicine through Cushing's syndrome, and with older HIV medicines.

Is a neck hump fat or bone?

It can be either. A fatty lump usually feels soft and may move slightly under the skin, while the bony bump is part of your spine; the most prominent one can be the sixth or seventh neck vertebra. If you're not sure, a GP can examine it.

What's the difference between a dowager's hump and a buffalo hump?

"Dowager's hump" is an old name for a rounded upper back in later life, sometimes from spinal fractures. "Buffalo hump" is a fat pad at the base of the neck, seen in Cushing's syndrome, with older HIV medicines and with overweight.

Can exercise get rid of a neck hump?

Not if it's fat. In most trials, exercising one area didn't remove fat from that area, and we found no study that tested exercise for a neck fat pad. If the hump is a rounded upper back, back-strengthening reduced the curve a little in trials.

Do chin tucks get rid of a neck hump?

We found no trial showing that. Chin tucks train the deep neck muscles and can move the head back a few degrees, but they don't burn the fat over the neck.

Is a neck hump a sign of insulin resistance?

It can go with metabolic problems: in a small series of 12 people with a buffalo hump who didn't have HIV, most had high blood pressure, diabetes or high cholesterol, and the authors suggested checking for them. If you have a fatty hump, ask your GP whether a health check makes sense.

Can steroid tablets cause a neck hump?

Yes. Taking high-dose steroid medicine for a long time is the commonest cause of Cushing's syndrome, which adds fat to the neck and upper back. Don't stop or cut down steroids yourself; talk to your doctor.

When should I see a GP about a neck hump?

See a GP about any new lump, and sooner if it's growing, hard, painful, red or hot. Go too if you also have a round red face, thin arms and legs, easy bruising or stretch marks, especially if you take steroids. A newly rounded upper back with back pain or height loss also needs checking, as it can be a spinal fracture.

Can a neck hump be removed?

A fatty hump can be removed by liposuction or surgery; in low-quality studies it came back after liposuction in about 1 in 10. On the NHS, a lipoma is usually only removed if it's growing or causing problems.

Is a neck hump permanent?

It depends on the cause. Treating Cushing's syndrome is the route for a steroid-related hump, and losing fat overall is the logical route for a fat pad, though we found no study measuring it. Fractured spinal bones keep their shape, and a posture-related curve changes a little with exercise.

Can a posture corrector fix a neck hump?

Braces change your position while you wear them, and we found no study showing a lasting change. They can't remove a fat pad.
