Typically, symptoms of non-IgE mediated CMA begin to occur within the first few months of life. The classic CMA presentation is blood in the stool. It can be associated with increased frequency of stool, looser consistency of stool and\/or mucus in the stool. The blood is generally flecked or streaked and appears red in colour (rather than maroon or brown). It is important to note that another common cause of blood in the stool at this age is constipation, which can happen from small tears at the anus from hard stool. However, with CMA, you\u2019ll notice the stool is most often soft or looser rather than hard.<\/p>\n\n\n\n
Other common signs of CMA may include:<\/p>\n\n\n\n
- \n
- Increased frequency of poops<\/li>\n\n\n\n
- Looser stool<\/li>\n\n\n\n
- Mucus in the stool<\/li>\n\n\n\n
- Gas or abdominal pain<\/li>\n\n\n\n
- Feeding refusal<\/li>\n\n\n\n
- Reflux or regurgitation<\/li>\n<\/ul>\n\n\n\n
Not all symptoms will occur immediately after feeding. Some symptoms may take anywhere between two days to one week to show up. If your baby is experiencing lethargy, dehydration, a high fever, or paleness of the skin, visit the emergency room for assistance. If possible, take a picture of the baby\u2019s stool, especially if it contains blood or mucus, to show your doctor to help them confirm a diagnosis.<\/p>\n\n\n\n
Nutricia has established a CMA allergy symptom checker<\/strong><\/a> <\/strong>to help serve as a starting point to help identify infants who may have CMA. Always check with your doctor or dietitian before modifying your baby\u2019s diet.<\/p>\n\n\n\n
Is there a cure for CMA?<\/h2>\n\n\n\n
As of now, there is no cure for CMA. However, there are ways to manage it and many babies outgrow their CMA as they get older and typically resolves by one year of age (4). Removing milk from the mother and baby\u2019s diet and\/or switching to extensively hydrolyzed formulas for babies who are formula-fed can help alleviate symptoms. Your doctor may recommend an oral food challenge to confirm a CMA diagnosis, where cow\u2019s milk protein is removed for a minimum of two weeks with symptom improvement\/resolution, followed by reintroduction of cow\u2019s milk with symptom deterioration (4).<\/p>\n\n\n\n
What Happens After a Diagnosis?<\/h2>\n\n\n\n
Babies and children that have been diagnosed with CMA require a milk-free diet. If the infant is being breastfed, the mother should talk with her healthcare provider about eliminating milk and potentially soy, from her diet. Hypoallergenic formula is needed with extensively hydrolyzed milk proteins if the baby is formula fed. Once a child has been diagnosed, a healthcare professional can help create a management plan.<\/p>\n\n\n\n
Remember to look at food labels carefully to avoid any possible allergens. When preparing food at home, be sure to clean surfaces that have been exposed to foods with an allergen to avoid cross-contamination.<\/p>\n\n\n\n
While CMA symptoms can be scary and cause alarm, it is important to note that once the cow milk is removed from the diet, babies otherwise continue to grow and thrive; they gain weight and continue to reach their developmental milestones!<\/p>\n\n\n\n
