Symptoms of Cow Milk Sensitivity

Tummy troubles, rashes and chronic congestion can all be caused by cow milk sensitivity. Here’s how to spot it, and how this common problem differs from cow milk allergy.

Signs and symptoms of cms

The terms “cow milk protein allergy” and “cow milk sensitivity” are often used interchangeably, though the prevalence and intensity of symptoms associated with each may be different.

Cow milk protein allergy (CMPA) affects 2-3% of children under one year while the prevalence of cow milk sensitivity is less defined in research. Clinical and parental observation suggests that many young children may have at least one symptom related to cow milk consumption.

Cow Milk Protein Allergy

Confirmed cow milk protein allergy (CMPA) can be a severe health problem. Children with ‘obvious’ CMPA will have an immediate reaction to cow milk that happens within hours of ingestion; for others, symptoms may delay. Symptoms will most commonly be moderate to severe in intensity and may include:

  • Swelling around the mouth
  • Difficulty swallowing
  • Vomiting and regurgitation
  • Diarrhea
  • Blood in the stool
  • Food refusal
  • Failure to thrive
  • Colic
  • Severe eczema, rashes or hives
  • In rare cases, anaphylactic shock

Cow Milk Sensitivity

Cow milk sensitivity may encompass the delayed, mild to moderate symptoms associated with consumption of cow milk.

Digestive symptoms may include:

  • Bloating
  • Gas
  • Abdominal pain
  • Colic
  • Loose stools
  • Constipation

Signs in the lungs and skin may consist of:

  • Non-illness related chronic runny nose
  • Non-illness related chronic cough
  • Non-illness related chronic congestion
  • Recurring ear infection
  • Eczema
  • Rashes

The Difference Between Cow Milk Sensitivity & Allergy

It can be difficult to tell the difference between allergy and sensitivity because symptoms may be similar. Many healthcare providers rely on the intensity of symptoms, serum (blood) IgE testing, and skin prick testing to guide their diagnosis. The gold standard diagnostic method for cow milk protein allergy is the ‘Oral Challenge Test’ involving the complete avoidance of cow milk, followed by a medically supervised reintroduction and monitoring of symptoms.

It’s important to know that goat milk-based foods, including baby formula, are not suitable for children with cow milk protein allergy (as they might also react to the protein in goat milk). Goat milk-based formula, such as Kabrita Goat Milk Formula, may be an alternative for little ones with mild symptoms related to cow milk consumption.

Since every child is different, we recommend speaking with your healthcare provider if you are concerned about whether your little one’s symptoms stem from allergy or sensitivity, and to discuss your feeding options.

Kabrita non-GMO Goat Milk Formula is designed to maintain the natural comfort of little ones during feeding transitions, such as weaning, supplementing or changing formulas due to skin or tummy troubles*. Join thousands of happy Kabrita Families and claim your free trial offer today!

  1. I may possibly have IBS and maybe should avoid dairy. I love milk and goat milk especially. I do not drink more than 12oz. A day. The past 10 years I have been trying to find out what causes intermittent diarhea . Should goatmilk be a problem?

    1. Hi Connie, thank you for your question. Your Healthcare provider would be the best person to guide you on whether he/she thinks goat milk could be suitable in your situation. Goat Milk is naturally easy to digest, however in cases of an allergy to dairy protein, Goat Milk would not be suitable. We wish you well!

  2. Would goatmilk be a problem with IBS WHICH I AM DEALING WITH THEST PAST YEARS.??it has been suggested that I avoid dairy, which I love

    1. Hi Connie, if your healthcare provider has suggested you avoid dairy perhaps you should try it to see if you notice any improvement in your symptoms. Wishing you the best!

  3. Daughter is 18 months old. She’s a bit underweight, but still thriving. Dr says she is fine. She doesn’t eat as Much as I’d like, but it is getting better. She goes through periods where her stool is very soft. Not technically diarrhea, but VERY soft. Lately she’s been skipping a poop every other day. There has never been blood in her stool and she doesn’t seem to be having tummy pains. Her eczema has flared up on her face as well. We have seen a GI dr and he said if the soft stool came back, we would test for a food allergy. I’m giving him a call this week, but could this be the problem?

    1. Hi Samantha, the best would be indeed for your Doctor to have a proper examination and share his thoughts on what could be the possible reason for the stool inconsistency and the eczema, and whether Kabrita may be a solution. Feel free to contact us in the future via email as well, we are able to reply quickly! All the best!

    1. Hi Morgan! I hope you’re doing well! Each baby is unique so the results might be different for your little one. However, according to the feedback we have received, most parents notice the difference within days of switching! Please let us know if you have any other questions and we would be happy to help!
