Gastroenteritis is caused by an infection of the Coxsackie virus. If symptoms of nausea are present, it is advisable to use antiemetic and antispasmodic medications, as well as antiviral medications for colds. Be mindful of weather changes, drink plenty of water, and maintain a light diet with soft, easy-to-digest foods during treatment. Avoid raw, spicy, and irritating foods. Combine work with rest to avoid excessive fatigue, and pay attention to emotional changes to avoid excessive anxiety and tension.

Symptoms of the common cold

The common cold usually manifests with symptoms such as runny nose, sneezing, sore throat, and coughing, often leading to a dry cough without significant phlegm. Additionally, the common cold may also accompany muscle aches, fatigue, and even headaches as general symptoms. Sometimes, patients with the common cold may also exhibit fever, though high fever is relatively rare. Regarding the common cold, the condition generally has a self-limiting nature, and symptomatic treatment usually leads to recovery. However, caution is still needed. Sometimes, the common cold can also coincide with pneumonia, although this is relatively rare. Close observation of the condition is necessary; if cold symptoms persist or are accompanied by high fever and purulent sputum, active investigation should be undertaken.

How to treat a cold in children?

Child cold, also known as acute upper respiratory tract infection, is a common disease in children, mainly manifested in inflammation of the mucous membranes of the nose, nasopharynx, and throat. It can lead to acute manifestations of rhinitis, pharyngitis, and tonsillitis in children. The treatment of a child's cold begins with general measures such as ensuring the child rests, drinks plenty of water, and avoids contact with others who have a cold to prevent complications. Symptomatic treatment is also important. For example, antipyretic analgesics can be used when a child has a high fever. If the high fever is accompanied by febrile convulsions, sedatives may be needed to control the convulsions. If nasal congestion is particularly severe, topical medications can be used to reduce congestion. For severe throat pain, throat sprays may be used. Etiological treatment is also necessary, as most colds are caused by a viral infection, so antiviral medications can be used. If the cold is severe and there is a secondary bacterial infection, antibiotics should be used under the guidance of a hospital doctor. If the child has a viral conjunctivitis along with a cold, antiviral eye drops can be used.

Can I eat watermelon if I have a cold and cough?

When suffering from a cold and cough, it is appropriate to eat some watermelon as it contains a lot of water which can help replenish the fluids the body needs. It also has a soothing effect on the throat. However, be careful not to eat too much because watermelon has a high sugar content. Excessive sugar intake can exacerbate coughing by increasing phlegm. Additionally, watermelon has cooling properties, so consuming too much can lead to gastrointestinal discomfort. Patients with weak spleen and stomach, already having frail gastrointestinal systems, may experience discomfort from consuming too much watermelon. It is recommended to eat moderate amounts and maintain a light diet, drink plenty of water, and consume more fruits like apples, pears, or grapefruits which are more suitable. It is crucial to actively cooperate with medical treatment during a cold and cough to alleviate symptoms.

What will happen if you take medicine for wind-heat cold when you have a wind-cold cold?

The treatment principle for colds caused by wind-cold is to use pungent and warm herbs to expel the pathogen through sweating and to disperse wind-cold. The medications for wind-heat colds mainly focus on using pungent and cooling herbs to expel the pathogen, and the treatment principles for the two are completely opposite. If medications for wind-heat cold are taken for a wind-cold cold, it might lead to a worsening of the trapped cold, causing mild fever, more severe headache, and body aches, along with nasal congestion and a runny nose with clear discharge. At this point, it is necessary to stop using the medication for wind-heat colds and switch to medications for wind-cold colds, or, if the condition is severe, seek a face-to-face consultation with a doctor.

How to distinguish a viral cold from a cold caused by exposure to cold weather

A cold caused by getting chilled can often present the same symptoms as a viral cold. This type of cold refers to a situation where, after exposure to cold, an individual's immune system becomes weakened, allowing pathogens residing in the respiratory tract to proliferate rapidly and thus cause a cold. In many cases, a cold from getting chilled is also viral in nature. Symptoms commonly seen in individuals with colds may include runny nose, sneezing, nasal congestion, sore throat, coughing, headache, muscle aches, fatigue, and sometimes a mild fever. However, sometimes a cold due to chilling may also lead to infection by other pathogens, such as bacteria, which can present clinically differently from a viral cold. In such cases, patients might not exhibit typical symptoms like clear nasal discharge or sneezing; instead, they might only show nonspecific upper respiratory symptoms. It is also possible for them to experience high fever, obvious sore throat, and swelling of the tonsils, which are signs of acute purulent tonsillitis, a specific type of bacterial cold.
