Symptom 14. Skin Rashes: The Uncommon Dermatological Manifestation of Diverticulitis
While it may seem unlikely that a disease affecting the digestive system could manifest on the skin, in some cases, patients with diverticulitis may develop skin rashes. This typically occurs in more severe cases when the infection or inflammation is not adequately contained within the digestive tract.
The link between diverticulitis and skin rashes can be explained by the body’s immune response. When the body fights off an infection, it releases a variety of substances that are designed to destroy the pathogens. Sometimes, these substances can cause inflammation in different parts of the body, including the skin.
In some cases, the rash may be a sign of an allergic reaction to certain medications used to treat diverticulitis. This can manifest as red, itchy, and bumpy patches on the skin, often appearing on the chest, arms, or back. It can be an immediate allergic reaction, or it may develop slowly over several days.
Additionally, chronic stress or anxiety associated with dealing with a long-term illness like diverticulitis may trigger or exacerbate certain skin conditions, such as eczema or psoriasis. This connection underscores the importance of managing psychological well-being in conjunction with physical health.
Finally, prolonged bouts of fever, another possible symptom of diverticulitis, can also lead to a rash. Fever rashes often appear as tiny red or pink spots on the skin. They are usually flat and may look like a sunburn. (14)
