Skin problems in horses come in many forms, for example (tail and mane) eczema, mud fever, scabies, an allergic or hypersensitivity reaction, a fungal infection, warts or skin cancer. They may be accompanied by itching, red skin, bumps, swelling, bald patches, flakes or lesions.
The skin is the body's largest organ and has several functions. An important function of the skin is to protect the body from external influences. Furthermore, the skin plays a role in ensuring a constant body temperature, obtaining information about touch and pain and forming vitamin D. Waste products are also excreted through the skin.
The health of the skin is closely linked to the immune system. With a properly functioning immune system, balanced protection against external influences takes place. Stress, which can have many causes, weakens the immune system. For example, due to physical pain, an unstable environment, lack of social contact, too little exercise and/or stress of the owner.
Furthermore, the lungs, colon and skin are closely linked. All three are responsible for the removal of waste products. While in the skin it takes place through the pores, in the lungs disposal takes place through exhalation and in the intestines through faeces. An excess of waste products can therefore cause skin problems.
