Lupus is an autoimmune condition in which the immune system attacks healthy tissues. Systemic lupus erythematosus (SLE), the best-known form, can affect joints, skin, blood cells, kidneys, lungs, heart and nervous system. Discoid lupus mainly affects the skin. Lupus is not contagious, and its severity varies widely.
Joint and muscle pain, profound tiredness and rashes triggered by sunlight are common. Other features can include mouth ulcers, hair loss, fever, swollen glands, headaches, chest pain and Raynaud’s phenomenon, in which fingers or toes change colour in response to cold or stress. Symptoms may flare for weeks and then settle into remission.
The condition affects more women than men and is more common in people of African, Caribbean, Asian or Chinese heritage. Hormonal changes, sunlight, infection and some medicines may influence symptoms, but no single food or lifestyle factor causes lupus.
Diagnosis and medical care
Diagnosis can take time because symptoms overlap with other illnesses. It generally combines clinical history with blood and urine tests; scans or other investigations may be needed if organs are affected. Regular monitoring helps detect anaemia and kidney involvement.
Treatment may include hydroxychloroquine, anti-inflammatory medicines, corticosteroids, immunosuppressants or biologic medicines. New chest pain, breathlessness, neurological symptoms, significant swelling or reduced urine output needs prompt medical advice.
Living well with lupus
High-factor sunscreen—at least SPF 50—protective clothing and avoiding intense sunlight can reduce photosensitive flares. Smoking can worsen lupus and cardiovascular risk. Activity should be paced but maintained where possible; physiotherapy may help with stiffness and deconditioning.
A balanced diet with vegetables, fruit, whole grains, legumes, fish and other suitable proteins supports general health. Calcium and vitamin D matter when sun exposure is limited or corticosteroids are used. Blanket exclusion of gluten or dairy is unnecessary unless coeliac disease, allergy or another clear indication exists.
People planning pregnancy should speak with their specialist first because lupus can affect pregnancy and some medicines need changing in advance.
Useful supplements
Supplements should be selected for the individual rather than used automatically. Product directions and advice from an appropriately qualified professional should take precedence over general information.
| Supplement | Effects |
|---|---|
| A multivitamin and mineral formula containing zinc, vitamin C, B vitamins and selenium | Supports normal energy metabolism, antioxidant protection, immune function and tissue repair when intake is inadequate. |
| A high-strength, multi-strain probiotic | Supports intestinal microbial balance, nutrient absorption and normal immune signalling. Evidence for changing lupus activity is not established. |
| Whole-leaf aloe vera juice | Traditionally used to support bowel regularity and soothe tissues, with proposed anti-inflammatory effects. Evidence is limited and laxative components can cause diarrhoea or interactions. |
| Krill oil | Provides EPA and DHA, used to form signalling compounds with anti-inflammatory effects. It can alter bleeding risk and should be checked with medicines. |
| Spirulina powder | Supplies antioxidant pigments and nutrients and may have prebiotic effects. Products require quality assurance, and immune-stimulating claims warrant caution in autoimmune disease. |
| Vitamin D3 | Corrects low status and supports bone, muscle and immune function. Testing and clinician-led dosing are sensible because both deficiency and excess matter. |
Alfalfa tablets or sprouts are often discouraged in lupus because L-canavanine may trigger lupus-like symptoms in susceptible people. No supplement should replace prescribed treatment or regular kidney and blood monitoring.
