Clinically, thick tongue moss is mainly seen in babies with food injuries and indigestion, which is often referred to as food accumulation, and some babies are born with thick tongue moss because of their constitution, which can be left alone for the time being if there are no clinical manifestations. First of all, indigestion can lead to thick and greasy tongue, because the baby is young, the spleen and stomach is relatively weak, inappropriate diet will lead to a thick and greasy tongue. For example, adding complementary foods too early and eating too much will cause bloating, abdominal pain and diarrhea due to indigestion, and then the baby’s tongue will be thick and greasy. You can take oral medication such as Mamie’s Love, Bifidobacterium, and Spleen Nourishing Granules to relieve the symptoms. For babies who are still breastfeeding, indigestion rarely occurs because breast milk contains unsaturated fatty acids and digestive enzymes, which can promote digestion, and indigestion rarely occurs, but there are some special circumstances, such as the mother has recently eaten more greasy or cold and spicy food, which will lead to the above symptoms in children. The symptoms will be relieved if the mother changes her diet to a lighter diet and avoids cold and spicy foods. In addition, some children do not have any injury, indigestion or food accumulation because of their special constitution, but they may have thick tongue coating.
