Even after recovering from a cold, one may still cough to the point of vomiting?


Hello, Dr.
Fei.
My daughter started experiencing coughing symptoms around the end of April.
At first, I didn't think much of it, but then she began to have phlegm and a runny nose, so I took her to a pediatric clinic for a cold.
During this time, she did not have a fever.
After finishing the first course of medication, she was still coughing, often to the point of vomiting what she had eaten.
I took her back to the pediatric clinic for a follow-up, and after the second course of medication, she still wasn't completely better; instead, her nasal discharge and phlegm started to turn slightly yellow.
Therefore, I took her to Chang Gung Memorial Hospital to see a pulmonologist because I had heard that a persistent cough could be due to a Mycoplasma infection leading to pneumonia.
However, after an X-ray and blood tests, the doctor said it wasn't Mycoplasma, but it could possibly be whooping cough.
The doctor mentioned that she would be completely better after finishing this course of medication, so we took the medication home.
However, there was still no significant improvement, so before finishing the Western medicine, I hurriedly took her to see a Chinese medicine practitioner.
After finishing the Chinese medicine, her nasal discharge and phlegm were gone, and she clearly had very little coughing.
However, today after eating some sweets, she started coughing heavily again, even to the point of vomiting.
After having some spicy food at night, she felt the urge to cough again, but she managed to hold it in; otherwise, she would have definitely vomited her dinner.
My daughter mentioned that when she looks up, there is a spot in her throat that feels very itchy.
(She usually doesn't cough immediately after eating; instead, she starts coughing vigorously about 5 minutes after finishing her food.) Doctor, do you think my daughter's symptoms resemble those of asthma? What exactly is whooping cough? If she continues to have these sudden bouts of severe coughing that lead to vomiting, which specialist should I take her to see? Thank you.

Hello: The reasons for a prolonged cough include infections, allergies, aspiration of foreign objects, and gastroesophageal reflux disease (GERD).
I recommend using cough suppressants and antiemetics concurrently, while also monitoring for any allergic tendencies.
Wishing you health and happiness.
Sincerely.

When it comes to persistent coughing in children, it can be a source of concern for parents, especially when the cough is accompanied by other symptoms such as phlegm, nasal discharge, or vomiting. In your daughter's case, it sounds like she has been experiencing a prolonged cough since late April, which has not responded well to initial treatments. This situation raises several important considerations regarding when to seek medical help and what might be causing her symptoms.

Firstly, it is essential to understand that a cough can be caused by various factors, including viral infections, bacterial infections, allergies, or even asthma. Given that your daughter has had a cough for an extended period, it is crucial to monitor her symptoms closely. The presence of yellow phlegm can indicate a bacterial infection, but it can also be a sign of a viral infection that is resolving. The fact that she has experienced vomiting due to coughing suggests that the cough is severe enough to cause distress and may require further evaluation.

You mentioned that your daughter was evaluated for mycoplasma pneumonia and was ruled out for this condition, which is a good step. The mention of whooping cough (pertussis) is also significant. Whooping cough is a highly contagious respiratory disease characterized by severe coughing fits that can lead to vomiting. It is essential to consider this diagnosis, especially if your daughter has not been vaccinated against it or if there is a known outbreak in your area.

The fact that your daughter experiences a tickling sensation in her throat when she looks up could suggest post-nasal drip, which is common in children with allergies or sinus issues. This can lead to coughing, especially after eating or when lying down. If she is experiencing coughing fits after consuming sweet or spicy foods, it may indicate a sensitivity or irritation in her throat, which could be exacerbated by certain foods.

Given the complexity of her symptoms, it is advisable to seek further medical evaluation. If her cough persists or worsens, or if she experiences difficulty breathing, wheezing, or any other concerning symptoms, you should take her to a pediatrician or a pediatric pulmonologist. A pediatric pulmonologist specializes in respiratory issues in children and can provide a more in-depth evaluation of her condition.

In addition to medical evaluation, consider keeping a symptom diary to track when the cough occurs, its severity, and any associated factors such as food intake, environmental triggers, or activities. This information can be invaluable for healthcare providers in diagnosing and managing her condition.

In summary, persistent coughing in children warrants careful monitoring and evaluation, especially when accompanied by other symptoms. Given your daughter's ongoing symptoms and the impact on her daily life, seeking further medical advice is essential. A pediatrician or specialist can help determine the underlying cause of her cough and recommend appropriate treatment options. It is always better to err on the side of caution when it comes to your child's health.
