No, a keloid isn't strictly classified as an autoimmune disease, but it involves significant immune system involvement, acting more like an auto-inflammatory or fibroproliferative skin condition where the immune cells and inflammatory signals drive excessive collagen production and fibrosis, similar to features seen in some autoimmune-related skin issues like scleroderma. The immune response in keloids is dysregulated, with various immune cells and cytokines stimulating fibroblasts to overproduce collagen, leading to the characteristic raised scar.
Further, keloid surveillance studies have demonstrated that keloids are more common in allergic and/or auto-immune diseases such as asthma or atopic dermatitis compared with the normal population.
To support keloid therapy, it is advisable to limit or avoid pro-inflammatory foods such as processed meats, sugary snacks, refined grains and alcohol in excess. These foods can contribute to systemic inflammation and may impede the healing process.
Accordingly, low serum and tissue 25-Hydroxyvitamin D and deficient tissue vitamin D receptors contribute to the pathogenesis of keloids. This can be partly mediated by dysregulation of the antimicrobial peptide; koebnerisin.
Caffeine can also act as an adenosine‐receptor antagonist, although it has been shown that adenosine and adenosine‐receptor agonists promote wound healing through stimulating angiogenesis and increasing ECM production 8, 9, 10. This would therefore imply that caffeine can interfere with the wound healing process.
They typically develop on the torso and sometimes on the face and earlobes. Although anyone can get them, keloids are more common among darker-skinned people. Keloids can be painful or itchy but aren't usually dangerous to a person's health. However, depending on where they are located, they can be a cosmetic concern.
Generally, they contain relatively acellular centers and thick, abundant collagen bundles that form nodules in the deep dermal portion of the lesion. Keloids present a therapeutic challenge that must be addressed, as these lesions can cause significant pain, pruritus (itching), and physical disfigurement.
The top 5 worst autoimmune diseases are giant cell myocarditis, granulomatosis with polyangiitis, systemic lupus erythematosus, multiple sclerosis, and type 1 diabetes. These diseases can cause a lot of harm and even death if not managed well.
Autoimmune diseases do tend to run in families, which means that certain genes may make some people more likely to develop a problem. Viruses, certain chemicals, and other things in the environment may trigger an autoimmune disease if you already have the genes for it.
The Antinuclear Antibody test, or ANA, is a blood test that can help diagnose autoimmune diseases like lupus. ANAs can bind and damage certain structures within a cell's nucleus(1).
The diseases that associate with an increased risk of keloid include: the Rubinstein‐Taybi syndrome (RSTS), the Ehlers‐Danlos syndrome, the Lowe syndrome, Goeminne syndrome and others.
Scleroderma is a chronic autoimmune disorder where the body attacks itself, causing the scarring and thickening of body tissues.
Keloid scars are more likely to develop on the earlobe, along the line of the jaw, on the shoulders and on the skin over the breastbone. They often appear after ear piercing and are more common in the upper part of the body. Keloid scars are however rare on the eyelids, the soles of the feet, palms and genitals.
It forms months to a year after the injury that caused it. The scar grows larger than the initial wound. Keloids don't fade over time. A dermatologist may offer treatments like corticosteroid injections or pressure garments to reduce its size and appearance.
The effect of sex hormones has been postulated as the reason for activated keloid growth during adolescence and/or pregnancy.
Symptoms of a keloid scar
Keloid scars are usually raised, hard, smooth and shiny. They can be skin colour, pink, red, purple, brown, or darker than the skin around them.

Background Keloids are proliferative fibrous growths that result from an excessive tissue response to skin trauma. Most keloids occur sporadically, but some cases are familial. However, the genetics of keloid formation have only rarely been documented, and the mode of inheritance is not known.
Keloids are more common in darker-skinned people, particularly those of African or Asian descent. In the United States, about one in 30 Black individuals will develop keloids; their risk is approximately 20-times higher than it is for people of European (white) ancestry.
Quick answer: The 2 hour coffee rule suggests waiting at least two hours after waking up before drinking your first cup of coffee. This guideline aligns with the body's cortisol levels, aiming to optimize both the effects of caffeine and the body's natural wakefulness cycle.
Some of the identified issues relating to caffeine consumption include: Caffeine can affect you neurologically. Recovery is focused on helping your mind and body recuperate from the damage that addiction inflicts. Caffeine consumption has been shown to alter dopamine production, serotonin and GABA.
