Clinical Signs & Symptoms
Since our inception in 2012, Lipodystrophy United has made accomplishments that have helped to build a supportive community of patients, improve the understanding of the burden of living with lipodystrophy, and expand awareness.
Visual Signs of Lipodystrophy
Acanthosis Nigricans
Hyperpigmented, velvety, thickened plaques typically affecting intertriginous areas such as the neck, axillae, and groin. Often reflects severe insulin resistance.
Abnormal Fat Distribution
Generalized or regional loss of subcutaneous adipose tissue, with possible ectopic or disproportionate fat accumulation in areas such as the face, neck, cervicodorsal region, or upper trunk.
Muscular Appearance and Prominent Veins
Apparent muscularity, particularly in the extremities, due to reduced subcutaneous fat. Superficial veins may appear prominent because of diminished adipose tissue coverage.
Eruptive Xanthomas
Yellowish papules or nodules, often pruritic or tender, typically associated with severe hypertriglyceridemia. Lesions may occur on the skin or near joints and can signal increased risk for pancreatitis.
Manifestations & Complications by System
Metabolic and Endocrine Complications
-
- Severe insulin resistance — with difficulty achieving glycemic control
- Lipoatrophic diabetes — often clinically resembling type 2 diabetes but driven by adipose tissue deficiency
- Severe hypertriglyceridemia — with increased risk of acute pancreatitis
- Hypoleptinemia — due to reduced adipose tissue mass
- Leptin resistance — where present, contributing to dysregulated appetite and metabolism
- Hypertension and increased cardiometabolic risk
Neurologic and Neuropsychiatric Features
-
- Hyperphagia — often severe and persistent
- Depression and anxiety — frequently related to chronic disease burden and altered appearance
- Body dysmorphic distress — or appearance-related psychological distress
- Headaches
- Chronic fatigue
- Sleep-disordered breathing — including obstructive sleep apnea
- Sensory symptoms — including numbness, paresthesias, or altered sensation
- Cognitive symptoms — impaired concentration, memory difficulties, or “brain fog”
Musculoskeletal Manifestations
-
- Balance impairment or gait instability
- Muscle weakness — including muscular dystrophy–like phenotypes in some subtypes
- Myalgia and chronic widespread pain
- Reduced mechanical cushioning — causing pressure-related pain when sitting or lying down
- Low bone mineral density — including osteopenia or osteoporosis
- Skeletal abnormalities — bone deformities, scoliosis, or bone cysts in selected subtypes
- Systemic inflammatory symptoms — in inflammatory or autoimmune-associated forms
Renal Complications
-
- Proteinuric kidney disease
- Glomerulonephritis — particularly in acquired or autoimmune-associated forms
- Chronic kidney disease — secondary to metabolic, vascular, or inflammatory complications
- End-stage kidney disease — potentially requiring dialysis or transplantation
Physical and Dermatologic Findings
-
- Generalized or partial lipoatrophy — affecting the face, limbs, trunk, or other regions depending on subtype
- Ectopic or regional fat accumulation — cervicodorsal, facial, neck, or intra-abdominal fat deposition
- Prominent muscularity — especially in the extremities, due to reduced subcutaneous adipose tissue
- Prominent superficial veins — due to loss of subcutaneous fat
- Acanthosis nigricans — reflecting severe insulin resistance
- Eruptive xanthomas — particularly in the setting of marked hypertriglyceridemia
Reproductive and Gonadal Manifestations
-
- Polycystic ovary syndrome–like phenotype
- Menstrual irregularity — oligomenorrhea or amenorrhea
- Hyperandrogenism — hirsutism, acne, or androgenic features
- Subfertility or infertility — related to metabolic and hormonal dysfunction
Immune and Inflammatory Associations
- Autoimmune disease — particularly in acquired forms of lipodystrophy
- Immune dysregulation
- Recurrent infections or delayed wound healing — where immune dysfunction or poor metabolic control is present
Cardiovascular Complications
- Accelerated atherosclerotic cardiovascular disease
- Cardiomyopathy — in selected genetic or syndromic forms
- Arrhythmias
- Heart failure — particularly in advanced cardiometabolic disease or cardiomyopathic subtypes
Gastrointestinal and Hepatic Complications
- Recurrent acute pancreatitis — secondary to severe hypertriglyceridemia
- Metabolic dysfunction–associated steatotic liver disease — including MASH
- Hepatic fibrosis or cirrhosis — in advanced disease
- Hepatomegaly
- Gastroparesis or delayed gastric emptying — particularly in patients with longstanding diabetes
- Esophageal dysmotility or dysphagia — where present in syndromic subtypes
Psychosocial and Quality-of-Life Impact
- Appearance-related distress and social anxiety
- Reduced quality of life — due to chronic symptoms, metabolic complications, pain, fatigue, and diagnostic delay
- Psychological burden — of living with a rare, often under-recognized disorder
