What is the reason for a 18-month-old baby suddenly crying non-stop?

Patient's question:

No

Doctor's answer:

Most babies suffer from colic, also known as infantile spasms. The symptoms are crying due to unknown factors or causes, turning red all over the face from exertion. The main reasons are: 1. Immature central nervous system development 2. Improper feeding 3. Allergic reactions to certain foods, such as milk, eggs, etc. 4. Inability to digest lactose in milk, leading to intestinal bloating and pain (common). Therefore, there is no need to be anxious or worried. Improvement in feeding methods can be adopted to avoid the baby swallowing air, or switching to low-lactose or hypoallergenic formula to reduce abdominal pain and diarrhea caused by gastrointestinal allergies. Gentle clockwise massage on the baby's abdomen can also help alleviate the pain.
Medical Advice: Due to underdeveloped gastrointestinal systems in infants, intestinal motility is often irregular, leading to bloating, gas, frequent crying. This condition is medically referred to as infantile colic.
Lifestyle Care: If the baby continues to cry uncontrollably, it is recommended to seek medical attention.
