When children catch a cold, bacteria or viruses may invade the gastrointestinal tract, affecting its function and causing a loss of appetite. Therefore, when children show symptoms of a cold, in addition to fever, runny nose, and cough, they may also experience poor appetite, abdominal pain, bloating, and even vomiting and diarrhea. When a child has a loss of appetite due to a cold, in addition to treating the symptoms with cold medicine, we can also provide a light diet, encourage more water intake, and give easily digestible, vitamin-rich foods. Additionally, administering Chinese herbal medicine to strengthen the spleen and stomach can be beneficial.

What are the symptoms of viral colds in children?

Symptoms of viral cold in children include nasal congestion, runny nose, sneezing, cough with phlegm, fever, headache, body aches, and sore throat. When having a cold, it is important to rest first, avoid strenuous exercise, and allow the body to focus its resources on the functioning of the immune system. It is also important to drink plenty of water, as all immune mechanisms rely on sufficient water. Drinking more water leads to more urination, which increases the excretion of water-soluble vitamins, so it is necessary to adequately supplement water-soluble vitamins, such as vitamin C and vitamin B. Fruits and vegetables are preferred. Additionally, symptomatic medication treatment should be applied.

How to treat children's colds, coughs, and phlegm

When children catch a cold and cough with phlegm, the first consideration should be whether there is bronchitis. If the cough is severe, expectorant and cough suppressing medications can be administered orally, such as traditional Chinese medicine or Western medicine, for example, ambroxol. Additionally, bronchitis might be accompanied by a bacterial infection, in which case anti-inflammatory drugs like cephalosporins or penicillin can be prescribed. Nebulizer treatment can also be used, which helps in thinning the mucus and suppressing cough. Furthermore, it might be necessary to conduct a routine blood test to assess the child's condition.

What should I do if a child has a cold with a persistent high fever?

For a minor cold accompanied by persistent high fever, firstly, it is essential to monitor body temperature. If the fever continues, the initial step should be to reduce the fever, which can be done by taking ibuprofen or acetaminophen orally every 4 to 6 hours as required. Additionally, physical cooling methods such as tepid sponge baths, warm baths, and drinking warm water can also be used. If the fever persists or recurs, it's crucial to visit a hospital for routine blood tests and C-reactive protein assessments to evaluate the condition and determine whether it is caused by a bacterial or viral infection. If a bacterial infection is suspected, sensitive antibiotics should be used to treat the infection. If a viral infection is considered to be the cause of the ongoing fever, treatment should primarily focus on fever reduction. Attention should also be paid to mental responses and changes in body temperature.

What medicine should a child take for vomiting and a cold?

When a child has a cold and shows symptoms of vomiting, it is likely due to acute gastrointestinal symptoms. In this case, oral medications to protect the stomach, such as bifidobacterium, cimetidine, omeprazole, or other antiemetic drugs can be administered. Additionally, it is important to check if there are symptoms of tonsillitis or throat inflammation, as inflammation of the tonsils or throat can stimulate the gag reflex and also cause reflex vomiting. In this situation, the first step should be to control the symptoms of the throat and tonsils, which will gradually improve the vomiting. Also, pay attention to the child's body temperature and their mental responses.

What to do if a child has a cold and is short of breath?

There are two common causes of shortness of breath in children with colds, and the corresponding treatments are as follows: First, shortness of breath in children with colds is mainly due to respiratory obstruction caused by cold symptoms, leading to blockages in the nasal mucosa. This can easily lead to breathing difficulties, so shortness of breath occurs. We can use warm, damp towels or drop vitamin AD drops into the nasal cavity, among other methods. A warm, damp towel can be placed near the nasal cavity, and the principle of water vapor evaporation can effectively alleviate the blockage of the nasal mucosa. Dropping vitamin AD drops into the nasal cavity can also effectively moisten and lubricate the nasal mucosa, relieving nasal blockages and thus improving symptoms of shortness of breath from a cold. The second cause of shortness of breath from a cold is due to myocarditis or cardiac damage following a viral cold. For mild cases, oral medications that nourish the heart muscle should be administered for treatment, and children must ensure they rest and avoid strenuous activity. For severe cases, intravenous infusions and medications that nourish the heart muscle are needed for treatment. (Please follow medical advice when using medications.)
