Babies with zinc deficiency are prone to catching colds, as zinc is an important trace element in the human body. When zinc is deficient, it significantly impacts the baby’s immune system, making them susceptible to catching colds, repeatedly suffering from respiratory infections, and experiencing a prolonged duration of illness.

Zinc plays a critical physiological role in the growth and development of the human body, regulates the development of the immune system, and is crucial for sexual maturation. Besides causing repeated respiratory infections, zinc deficiency can also lead to stunted growth and development. Zinc-deficient babies are noticeably shorter and weigh less than their peers, potentially leading to poor appetite, anorexia, and even pica, a condition where children may crave non-food items like paper, soil, or coal slag.

Zinc-deficient children are also prone to various types of dermatitis, such as mouth ulcers, glossitis, and various skin diseases. In severe cases of zinc deficiency, it can lead to delayed development of secondary sexual characteristics.

Is it serious to catch a cold in early pregnancy?

In the early stages of pregnancy, if a pregnant woman catches a cold, it generally does not affect the fetus unless it is particularly severe, such as having a high fever. In day-to-day life, it is important to drink plenty of water, rest, avoid overexertion, enhance nutrition, and eat light, easily digestible foods. These measures can typically alleviate the condition on their own. However, if a cold occurs again and the symptoms are severe, such as high fever or intense coughing, it is necessary to seek timely treatment at a reputable hospital. During a cold, it is advised to avoid medication unless absolutely necessary, in which case medication should only be used under the guidance of a doctor.

Stages of Cold Symptoms

The symptoms of a cold generally fall into three stages. Initially, the symptoms of a cold may be mild or even absent, such as slight sneezing, runny nose, or nasal congestion. In such cases, it is advised to drink plenty of water, promote excretion, and improve immunity, as the early symptoms are often mild or not obvious and hence overlooked. Later, the symptoms of a cold get more severe. During the mid-stage of a cold, symptoms may worsen, including cough, phlegm, sore or swollen throat, or itchy and dry throat. Body temperature may also rise slightly. At this stage, it is recommended to actively follow a doctor's advice and take appropriate anti-inflammatory and anti-infection medication, along with fever-reducing and cough-relieving drugs to alleviate the symptoms. In the later stages of a cold, symptoms may improve, for example, the phlegm may turn yellow and the headaches and fever may subside. Under these conditions, it is sufficient to continue taking medication under a doctor’s guidance for treatment.

Sore throat without cold symptoms

If it is just a simple sore throat without any other cold symptoms, it could possibly be due to an early stage cold, acute pharyngitis, acute laryngitis, acute tonsillitis, or acute epiglottitis. Some patients may also experience neurogenic pain in the throat area. Overall, there are many possible causes, and it's hard to determine based solely on symptoms. Therefore, it is recommended to visit an ENT (Ear, Nose, and Throat) specialist, who can perform an indirect laryngoscopy or a fiber optic laryngoscopy to clearly observe the specific condition and location of the disease within the throat. Additionally, a complete blood count test can be helpful in determining whether there is an acute bacterial or viral infection causing inflammation. If there is an acute infection causing inflammation, antibiotic treatment may be considered, along with regular follow-ups.

What should I do if I have a cold with headache and fever?

When experiencing symptoms of a cold such as headache and fever, one should first measure their body temperature and adopt corresponding treatment measures based on the severity of the fever. Fever can cause headaches, fatigue, body aches, and may even lead to complications like nausea and vomiting. If the body temperature does not exceed 38℃ (100.4°F), one can take vitamin supplements, drink ginger tea, and use physical methods to reduce fever. If the body temperature is above 38℃ (100.4°F), one may consider taking antipyretic and pain-relieving medications like ibuprofen or aspirin to alleviate symptoms. Generally, once the body temperature returns to normal, headache symptoms will gradually improve or disappear. (The use of medications should be based on specific conditions and under the guidance of a doctor.)
