Recognizing Lactose Intolerance in Children and Suitable Foods

The primary source of nutrition for infants in the early years is milk. Most newborns will exclusively breastfeed, while some may receive supplemental formula. Unfortunately, some children may suffer from lactose intolerance. So, what are the signs of lactose intolerance in children, and what foods can they eat?

1. Understanding lactose intolerance in children

Before delving into how to recognize lactose intolerance in children, let's have a general understanding of this condition. Lactose is a type of sugar found in breast milk and milk from mammals such as goats and cows. Lactose contributes to the characteristic sweet taste of milk, and most animal milk and its derivatives contain this sugar.

Children with lactose intolerance experience difficulty digesting lactose

In order for the body to digest or absorb lactose, the digestive mucosa needs to produce a specific enzyme called Lactase. It helps break down lactose into two simple sugars small enough for the body to absorb into the general circulation. In infants, the body secretes enough Lactase enzymes to break down all the lactose in breast milk. Over time, a child's body will produce less and less Lactase.

The condition of lactose intolerance occurs when the digestive system does not produce enough Lactase, so the lactose in the milk is not properly digested. As a result, the excess lactose moves down to the colon. There, bacteria in the colon use lactose and convert it into carbon dioxide and lactic acid. While not causing severe health risks, this condition leads to uncomfortable symptoms for the child. If left untreated, it can negatively impact nutrient absorption and the child's overall development. Therefore, early detection and management of this condition are crucial for the child's well-being. Parents, let's explore how to identify lactose intolerance in children in the following section.

2. Methods to identify lactose intolerance in children

Typically, children with lactose intolerance will show digestive symptoms. These signs occur 30 minutes to 2 hours after the child consumes milk or lactose-containing products. So, how to identify lactose intolerance in children? Parents can easily observe the following indicators:

Identifying lactose intolerance: Diarrhea after milk consumption

Child experiences loose stools: Undigested lactose enhances water drainage in the colon, resulting in increased bowel movements. Stools become loose, with a sour smell, frothy appearance, and may contain mucus. The acidic nature of the stools can lead to diaper rash around the anus over time.

Baby feels bloated, abdominal discomfort: The carbon dioxide produced when lactose is consumed by bacteria in the colon can cause bloating, abdominal discomfort, and gassiness in the child.

Another way to identify lactose intolerance in children is if they vomit or regurgitate milk after consumption. The child's bloated and gassy abdomen may indicate a reduced capacity to hold milk. Stimulated bowel movements push milk back into the esophagus, causing the child to feel nauseous and vomit shortly after the next milk intake.

Abdominal pain, the child is fussy: Infants express their physical condition through crying. Therefore, identifying lactose intolerance in children involves incessant crying, reluctance to suckle, reluctance to eat, decreased playfulness, and accompanying symptoms. Older children may exhibit more pronounced signs such as clutching the stomach, flushed face, clenching fists and legs, and arching the back.

3. Why do children experience lactose intolerance?

After understanding how to identify lactose intolerance in children, mothers should explore the reasons behind this condition. Each cause requires different approaches to manage effectively.

3.1. Congenital Lactose Intolerance in Babies

The incidence of congenital lactose intolerance in children is not high. In this case, the child's body hardly produces lactase enzymes. The cause may be genetic, passed down through multiple generations from both parents. Additionally, premature infants have a higher risk of congenital lactose intolerance because their bodies cannot produce enough lactase enzymes on their own.

3.2. Primary Lactose Intolerance

The most common cause of lactose intolerance in children is when the infant's small intestine lacks the ability to produce enough lactase enzymes from birth. Along with this, the amount of lactase enzyme secreted decreases as the body matures, affecting the digestion of dairy products later in life.

3.4. Damage to the Immature Intestine Causing Lactose Metabolism Disorders

Originating from gastrointestinal trauma or after the child undergoes certain types of surgeries involving the removal of parts of the digestive system. It may also result from diseases such as intestinal infections caused by bacteria or viruses, Celiac disease, genetic mutations, Crohn's disease, etc.

Some Causes of Lactose Intolerance in Children

These conditions damage the immature intestine, hindering the production of Lactase enzymes. However, the ability to secrete Lactase enzymes may gradually recover after addressing the underlying causes mentioned above. Nevertheless, the treatment and recovery period can be lengthy, during which mothers should limit the use of milk and dairy products for their child.

4. Foods Suitable for Lactose-Intolerant Children

Thanks to recognizing lactose intolerance in children, parents can determine if their child is affected. If diagnosed, there's no need to worry excessively. By eliminating lactose-containing foods and establishing a well-balanced diet, the child can still grow healthy and thrive every day.

Children with lactose intolerance can consume alternative milk types and dairy-free products, such as:

Children with lactose intolerance can opt for nut milk instead of cow's milk

Children with lactose intolerance can opt for nut milk instead of cow's milk

If you're concerned that your child may lack calcium without consuming dairy and dairy products, consider the following foods:

• Calcium-rich vegetables: Leafy greens, broccoli, kale, peas, tofu, etc.
• Nuts and seeds: Almonds, chia seeds, flaxseeds, walnuts, macadamia nuts, etc.
• Fatty fish: Salmon, mackerel, sardines, etc.
• Seafood: Shrimp, crab, clams, etc.
• Additionally, consult with an expert on recognizing lactose intolerance in children to ensure your child's health. Use this information to create a nutritional plan that provides all the necessary nutrients for your child every day.

Thus, the article has shared information on recognizing lactose intolerance in children and suggested foods for lactose-intolerant kids. While a child's nutrition plan has its principles, it remains flexible in adjusting and selecting foods to ensure a well-balanced and nutrient-rich diet. Therefore, explore and establish a scientific, complete, and balanced nutrition plan for your child.
