Diet modification
The level of ability to digest sucrose or starch sugars is unique to each person who is living with CSID and depends on many factors, including the following:
The individual level of function of the digestive enzyme sucrase-isomaltase
How well the other functions of the gastrointestinal tract are working
How much sucrose and starch sugars are consumed
If a person has any other health issues that may affect digestionFor these reasons, a restriction diet needs to be specific for each patient who has CSID. Before making any changes to the diet, it is important for a patient to speak with a healthcare provider, especially if the patient is underweight or not gaining weight as would be expected. It is also advised that the patient work with a registered dietitian or nutritionist who can help identify the foods that can be tolerated and those that cannot be tolerated. A registered dietitian or nutritionist can also help the patient plan a diet that will meet the nutritional needs for normal growth and development. Vitamins, minerals, and additional supplements may be needed to meet all nutritional needs. Epidemiology
The highest prevalence rates are seen in the Inuit populations of Greenland (5–10%), Alaska (3–7%), and Canada (about 3%). European descent prevalence ranges from 0.2% to 0.05%. There is a lower prevalence reported in African Americans and Hispanics compared to Caucasians. See also

Collagen, used in wound repair, tends to overgrow in this area, sometimes producing a lump many times larger than that of the original scar. They can also range in color from pink to red. Although they usually occur at the site of an injury, keloids can also arise spontaneously. They can occur at the site of a piercing and even from something as simple as a pimple or scratch. They can occur as a result of severe acne or chickenpox scarring, infection at a wound site, repeated trauma to an area, excessive skin tension during wound closure or a foreign body in a wound. Keloids can sometimes be sensitive to chlorine. If a keloid appears when someone is still growing, the keloid can continue to grow as well. Location
Keloids can develop in any place where skin trauma has occurred. They can be the result of pimples, insect bites, scratching, burns, or other skin injury. Keloid scars can develop after surgery. They are more common in some sites, such as the central chest (from a sternotomy), the back and shoulders (usually resulting from acne), and the ear lobes (from ear piercings). They can also occur on body piercings.The most common spots are earlobes, arms, pelvic region, and over the collar bone. Cause
Most skin injury types can contribute to scarring. This includes burns, acne scars, chickenpox scars, ear piercing, scratches, surgical incisions, and vaccination sites. According to the (US) National Center for Biotechnology Information, keloid scarring is common in young people between the ages of 10 and 20.
