Why do children with colds have a lot of eye discharge?
Increased eye discharge in children with colds is primarily due to congestion and swelling of the nasal mucosa during a cold, which blocks the nasolacrimal duct. At the same time, pathogenic microorganisms from the nasal cavity can enter the eyes through the nasolacrimal duct, causing conjunctivitis, which leads to increased eye discharge. Therefore, when a child shows symptoms of a cold, it is important to maintain cleanliness and hygiene of the eyes. If nasal congestion is severe, medication should be administered under the guidance of a doctor to reduce the chance of developing conjunctivitis. If there is excessive eye discharge, eye drops can be used locally to alleviate the symptoms.
Why does the baby's umbilical hernia make a sound when pressed?
When pressing on a baby's umbilical hernia, a sound may be heard, primarily because the contents of the hernia are the intestines, most commonly the small intestine. Digestive fluids and gases are present in the intestines, so when pressed, the movement of gas through the digestive fluid can easily produce a sound, which is normal. The occurrence of an umbilical hernia in babies is mainly due to the incomplete development of the abdominal wall muscles and the umbilical ring not being fully closed. This allows internal organs like the intestines and mesentery to protrude through the umbilical ring, leading to symptoms of an umbilical hernia. After the appearance of an umbilical hernia, most children's hernias close on their own within the first year, with only a minority requiring surgical treatment.
Is infant thrush related to athlete's foot?
Infant thrush and athlete's foot are not highly related. Thrush is an oral infectious disease caused by Candida albicans infection, while athlete's foot is a local superficial skin fungal infection caused by fungi such as Trichophyton rubrum and Trichophyton mentagrophytes. The pathogens of the two are different and are not related. Thrush is a common oral infectious disease in infants and young children, mostly due to poor immune function in children, lack of oral hygiene, incomplete sterilization of bottles and pacifiers, or contact with children suffering from thrush.
Does a baby snoring mean that the adenoids are enlarged?
Baby snoring cannot necessarily be attributed to enlarged adenoids; it might also be due to a cold, nasal congestion, enlarged tonsils, or the position of the tongue falling back while sleeping. Therefore, the specific cause of a baby's snoring needs to be determined by a professional physician's examination, and appropriate treatment should be given based on the specific cause. If the snoring is due to enlarged adenoids or tonsils, a professional evaluation may be required to decide whether surgery is necessary to alleviate the symptoms of snoring. If the cause is nasal congestion, oral antihistamines or local nasal sprays can be used to relieve the symptoms of snoring. (If medication is required, please proceed under the guidance of a doctor.)
What should I do if a child suffers from food retention, vomiting, and diarrhea?
When children experience vomiting and diarrhea due to food stagnation, it is best to take them to the hospital for treatment. Through traditional Chinese medicine's syndrome differentiation and corresponding medicinal treatments, one can orally administer ready-made Chinese medicines that eliminate food stagnation. At the same time, probiotics can be taken orally to regulate the intestines. In terms of diet, it is advisable to focus on light, easily digestible, and nutritious foods. Avoid greasy, fried foods, seafood, and spicy or irritating foods. It is beneficial to eat small, frequent meals, avoid strenuous activities, and keep the child's abdomen warm to prevent catching cold.
Will pediatric allergic eczema be contagious?
Childhood allergic eczema is not a contagious disease, so it is not transmissible. Eczema is a common skin allergic disease during infancy and early childhood, characterized by rashes and skin itching. The rash mostly appears on the neck, the perineum, and other areas, often recurring. The onset in some children is related to family genetics. When children develop eczema, they can apply calamine lotion topically or take antihistamine medication orally under the guidance of a doctor to relieve symptoms of skin itching. In terms of diet, it is advisable to avoid allergenic foods such as fish, shrimp, eggs, and seafood.
What to do about nasal congestion in children after a cold?
After a child catches a cold and exhibits symptoms of nasal congestion, antihistamine medication can be taken orally under the guidance of a doctor to relieve nasal congestion. Local use of nasal drops or saline solution, or the use of nasal spray locally can also relieve symptoms of nasal congestion. When a child has a cold causing nasal congestion, it is mostly because the nasal mucosa becomes congested and swollen after the cold, leading to the symptoms of nasal congestion. Some children may develop symptoms of allergic rhinitis after a cold. In addition to nasal congestion, most children may also experience symptoms such as a runny nose and sneezing.
Why can't you cry with an umbilical hernia?
In children with umbilical hernia, crying can easily lead to an increase in intra-abdominal pressure. As the intra-abdominal pressure increases, gas in the intestines and mesentery can easily protrude through the unclosed umbilical ring, thereby exacerbating the symptoms of the umbilical hernia. In severe cases, this could lead to serious complications such as incarceration of the hernia. Therefore, in addition to not crying, children with an umbilical hernia should also avoid constipation, coughing, and vigorous activities that could increase intra-abdominal pressure, in order to prevent worsening of the hernia symptoms. In daily life, their diet should be light and easy to digest.
The umbilical hernia in the baby healed, but occurred again after two months. What should I do?
The baby's umbilical hernia had healed for two months but reappeared, indicating that the umbilical ring has not closed and the hernia has not completely healed. Therefore, in daily life, it is important to minimize the child's crying, tantrums, and vigorous exercise, and avoid getting cold or sick as much as possible to prevent severe coughing. Attention should be paid to the intake of foods rich in vitamins and cellulose, such as fresh vegetables and fruits. Drink plenty of water, maintain smooth bowel movements, and follow a light diet. Avoid eating cold and spicy foods.
Can an umbilical hernia often be pressed with hands?
Umbilical hernias can often be pressed with the hand, but it is important to be careful with the technique and strength used to avoid damaging the contents of the hernia or the local skin, which could lead to a secondary bacterial infection. Umbilical hernia is one of the common diseases during the newborn and infant periods. After the umbilical cord falls off, if the closure of the umbilical ring is incomplete or the tissues around the navel are not sturdy, factors such as frequent crying or constipation can increase intra-abdominal pressure. This can lead to the protrusion of abdominal contents, particularly the small intestine along with the peritoneum and abdominal wall skin, gradually pushing outward at the umbilicus, forming an umbilical hernia.
