Vomiting and diarrhea?


I accidentally drank a bottle of expired yogurt yesterday (November 30), and now I have been experiencing continuous vomiting and diarrhea.
The diarrhea isn't too severe, as I go to the bathroom about three times a day.
However, the feeling of nausea persists, and I feel too weak to go to work.
What should I do?

Hello: Based on the symptoms, it appears to be acute gastroenteritis caused by expired yogurt, resulting in vomiting and diarrhea.
It is recommended to visit a hospital for evaluation, and if necessary, to receive intravenous fluids (to replenish hydration and electrolytes) along with other medical treatments.
Wishing you good health.
Sincerely, Dr.

More Info


Dealing with vomiting and diarrhea after consuming expired yogurt can be quite distressing. It’s important to understand that consuming expired dairy products, like yogurt, can lead to foodborne illnesses due to the growth of harmful bacteria. The symptoms you are experiencing—vomiting and diarrhea—are common reactions of the body trying to rid itself of the toxins or pathogens ingested.


Immediate Steps to Take
1. Stay Hydrated: One of the most critical aspects of managing vomiting and diarrhea is to stay hydrated. When you vomit or have diarrhea, your body loses fluids and electrolytes, which can lead to dehydration. Drink plenty of clear fluids such as water, broth, or oral rehydration solutions (ORS) that contain electrolytes. Avoid caffeinated or alcoholic beverages as they can worsen dehydration.

2. Rest: Your body needs energy to fight off any potential infection or to recover from the effects of the expired yogurt. Make sure to rest as much as possible.

3. Dietary Adjustments: Once you feel ready to eat, start with bland foods that are easy on the stomach. The BRAT diet (Bananas, Rice, Applesauce, Toast) is often recommended for such situations. Avoid dairy products, fatty foods, and anything spicy until you feel better.

4. Monitor Symptoms: Keep an eye on your symptoms. If vomiting persists for more than 24 hours, or if you experience severe abdominal pain, high fever, or signs of dehydration (such as dizziness, dry mouth, or reduced urination), seek medical attention promptly.


When to Seek Medical Attention
- Persistent Vomiting: If you cannot keep any fluids down for more than 24 hours, you may need medical intervention to prevent dehydration.

- Severe Diarrhea: If you experience more than six watery stools in a day or if diarrhea lasts more than two days, consult a healthcare provider.

- Signs of Dehydration: Look for symptoms such as extreme thirst, dry mouth, little or no urination, severe weakness, or dizziness.

- Fever: A high fever (over 101°F or 38.3°C) may indicate a more serious infection that requires medical evaluation.


Understanding the Cause
The symptoms you are experiencing could be due to a few different factors:
- Bacterial Contamination: Expired yogurt can harbor bacteria such as *Listeria*, *Salmonella*, or *E. coli*, which can cause gastrointestinal distress.

- Food Intolerance: If you are lactose intolerant, consuming yogurt—even if it were fresh—might lead to similar symptoms.

- Viral Infections: Sometimes, symptoms can be exacerbated by a viral infection, which may coincide with your consumption of expired food.


Prevention for the Future
To avoid similar situations in the future, always check the expiration dates on food products before consumption. Additionally, ensure that dairy products are stored properly in the refrigerator and consumed within a reasonable time frame after opening.

In summary, while your symptoms are likely a result of consuming expired yogurt, managing hydration and monitoring your condition are key. If symptoms worsen or do not improve, do not hesitate to contact a healthcare professional for further evaluation and treatment.
