Lipedema and Fibromyalgia: Understanding the Overlap

Many people with lipedema have also been diagnosed with fibromyalgia — or have symptoms that suggest it even without a formal diagnosis. The overlap is well-recognised in clinical practice, if not yet fully explained by research. Understanding what each condition involves, where they share territory, and how they differ is useful both for navigating diagnosis and for managing symptoms that seem impossibly tangled.

What is fibromyalgia?

Fibromyalgia is a chronic condition characterised by widespread musculoskeletal pain, fatigue, cognitive difficulties (often called "fibro fog"), and sleep disturbance. Unlike lipedema, fibromyalgia does not involve visible changes to tissue — there is no abnormal fat, no swelling pattern, and no disproportionate body shape. The pain in fibromyalgia is thought to arise from central sensitisation: a state in which the nervous system amplifies pain signals, making stimuli that would normally be non-painful feel painful, and ordinarily painful stimuli feel more intense.

Fibromyalgia is diagnosed clinically, based on widespread pain across multiple regions of the body, symptom duration of at least three months, and the exclusion of other conditions that could explain the findings. Historically, the diagnosis relied on tender point examination; current diagnostic criteria (the 2016 ACR criteria) use symptom questionnaires that assess the spread of pain and severity of accompanying symptoms.

Fibromyalgia predominantly affects women — a pattern it shares with lipedema — and is associated with other conditions including irritable bowel syndrome, interstitial cystitis, anxiety, and hypermobility spectrum disorders.

How they overlap

Widespread pain with tenderness

Both conditions cause pain that is often worse on pressure or touch. In lipedema, this tenderness is localised to areas of affected fat tissue — typically the legs, thighs, hips, and sometimes the arms. In fibromyalgia, the pain is widespread and not anatomically tied to a specific tissue type.

In practice, when both are present, it can be genuinely difficult to establish which condition is driving a given pain experience — particularly when lipedema is more widespread or when fibromyalgia involves its most tender areas in the lower limbs.

Fatigue

Fatigue is prominent in both conditions. In lipedema, fatigue is thought to arise from the effort of carrying heavy, painful tissue, from disrupted sleep, and possibly from the inflammatory burden of the condition itself. In fibromyalgia, fatigue is a primary symptom, driven partly by sleep disruption and partly by the condition's effects on energy regulation.

When both are present, fatigue is typically more severe than with either condition alone and often more resistant to management.

Sleep disruption

Sleep is impaired in both lipedema and fibromyalgia, though through partially different mechanisms. Lipedema disrupts sleep through pain, limb heaviness, and heat sensitivity. Fibromyalgia disrupts the deep stages of sleep through abnormal brain activity patterns, producing unrefreshing sleep even when hours slept are adequate.

Cognitive symptoms

"Brain fog" — difficulty with concentration, word-finding, and short-term memory — is a recognised feature of fibromyalgia. People with lipedema also report cognitive difficulties, though whether this is a feature of lipedema itself, a consequence of poor sleep, or a reflection of co-occurring fibromyalgia is often unclear.

Hypersensitivity

Some people with lipedema describe generalised hypersensitivity — heightened response to sensory input more broadly, not just in affected tissue. Allodynia (pain from stimuli that are normally non-painful, such as light touch) is a fibromyalgia feature that can be present in lipedema patients beyond what lipedema tissue tenderness alone would explain. This may reflect central sensitisation as a shared or co-occurring mechanism.

Why they may co-occur

The reason for the co-occurrence of lipedema and fibromyalgia is not yet established, but several mechanisms are plausible:

Chronic pain driving central sensitisation. Persistent, undertreated pain — common in lipedema, where diagnosis is often delayed for years or decades — is a known driver of central sensitisation. Prolonged pain signalling from lipedema tissue could, over time, produce the sensitisation that is the hallmark of fibromyalgia.

Shared hormonal and inflammatory biology. Both conditions predominantly affect women and are associated with hormonal fluctuations. Systemic inflammation is a feature of lipedema, and inflammatory mechanisms have been proposed in fibromyalgia pathophysiology.

Shared genetic predisposition. Some of the conditions that cluster with fibromyalgia — such as hypermobility spectrum disorders — also appear more commonly in people with lipedema. Whether there is a shared genetic vulnerability is unknown but under investigation.

Diagnostic timing and recognition. It is also possible that some of what is diagnosed as fibromyalgia in the context of undertreated lipedema represents pain that is primarily lipedema-driven but distributed widely enough to meet fibromyalgia diagnostic criteria. Better lipedema treatment, in these cases, might substantially reduce what presents as fibromyalgia symptoms.

Implications for diagnosis

If you have lipedema and are experiencing widespread pain that goes beyond your affected tissue, fatigue that seems disproportionate, significant cognitive symptoms, or allodynia, it is worth raising fibromyalgia explicitly with your clinician.

Conversely, if you have a fibromyalgia diagnosis but have never been assessed for lipedema — particularly if you have always had disproportionate fat distribution in the lower body, sensitivity in the legs or arms specifically, or a relevant family history — it is worth asking about lipedema. The two conditions are not mutually exclusive, and treating only one while missing the other produces suboptimal outcomes.

Managing both conditions together

When both lipedema and fibromyalgia are present, management involves elements of both.

Pain management requires approaches that address both tissue-based lipedema pain (compression, movement, anti-inflammatory strategies, possibly liposuction) and centrally-driven fibromyalgia pain (low-dose medications that modulate central pain processing, such as duloxetine, amitriptyline, or pregabalin; and non-pharmacological approaches including cognitive behavioural therapy and graded activity).

Sleep is a treatment target, not a side note. Poor sleep worsens both conditions. Addressing sleep proactively — not just as a consequence of pain but as an active management goal — produces dividends across both conditions.

Pacing is important. The post-exertional malaise sometimes seen in fibromyalgia (and in conditions that co-occur with it, like ME/CFS) means that standard exercise-intensity guidance for lipedema needs to be applied carefully. Building activity very gradually, monitoring responses over 24–48 hours rather than immediately, and not pushing through significant post-exertional worsening is the right approach.

Multidisciplinary care is more valuable with overlapping conditions. Having a team that includes someone experienced in lipedema, someone managing the fibromyalgia component, and — ideally — a physiotherapist or pain specialist who understands both is significantly better than managing through isolated specialists.

Tracking becomes especially important when conditions overlap, because it allows you to identify which symptoms are moving in which direction with which interventions — information that gets lost very quickly without a record.

Frequently asked questions

Can you have both lipedema and fibromyalgia? Yes — lipedema and fibromyalgia frequently co-occur. Both predominantly affect women, both involve chronic pain and fatigue, and both are often underdiagnosed. Having one does not cause the other, but they share some possible underlying mechanisms including hormonal influences and chronic inflammation, and persistent undertreated lipedema pain may contribute to the central sensitisation that characterises fibromyalgia.

How do you tell the difference between lipedema pain and fibromyalgia pain? Lipedema pain is localised to areas of affected fat tissue — typically the legs, thighs, hips, and sometimes the arms — and is specifically tender to pressure on the tissue itself. Fibromyalgia pain is widespread across multiple body regions and is not anatomically tied to a specific tissue type. In practice, when both are present, distinguishing them can be genuinely difficult. A specialist assessment — ideally by someone familiar with both conditions — is the most reliable way to identify what is driving which symptoms.

Does lipedema cause fibromyalgia? Lipedema does not directly cause fibromyalgia, but prolonged, undertreated pain from any source — including lipedema — is a known driver of central sensitisation, which is the mechanism underlying fibromyalgia. This means that people whose lipedema goes undiagnosed and unmanaged for years may be at higher risk of developing central sensitisation patterns.

What medications are used when lipedema and fibromyalgia overlap? Fibromyalgia is sometimes treated with medications that modulate central pain processing — such as duloxetine, amitriptyline, or pregabalin. These address the neurological amplification of pain signals and are distinct from the compression, movement, and dietary approaches used for lipedema. When both conditions are present, management typically involves elements of both, and coordination between clinicians is important.

Is exercise safe when you have both lipedema and fibromyalgia? Exercise is beneficial for both conditions, but when fibromyalgia is involved, the risk of post-exertional symptom worsening is higher. A very gradual approach — starting with low-intensity movement such as water exercise or gentle walking, monitoring symptoms over 24–48 hours after each session, and building slowly — is safer than standard exercise intensity recommendations. Pacing is particularly important.
