Abdominal pain after quitting late-night snacks?


Hello, doctor.
Due to my work, I have developed a habit of eating late-night snacks.
Recently, I started to cut out late-night snacks because I am worried about gaining weight.
When I feel hungry, I try to endure it and go to sleep.
However, when I wake up the next day, I often have stomach pain and diarrhea.
Sometimes I wake up without diarrhea, but my gastrointestinal tract feels very uncomfortable, and my bowel movement schedule has changed; I used to have a regular urge to go around 2 or 3 AM, but now I feel the urge around noon, and my stools are usually softer.
If I wake up with stomach pain but no diarrhea, I sometimes need to rush to the bathroom after lunch.
However, if I eat a late-night snack, everything seems normal; I go to the bathroom at my usual time of 2 or 3 AM, and my stools are normal and not soft.
I have had gastrointestinal issues since childhood, and I also experience diarrhea when I am nervous during exams.
What could be the situation I am experiencing? How can I improve it? I also don’t want to gain weight from eating late-night snacks.
Thank you, doctor.

Based on the symptoms, the likelihood of irritable bowel syndrome (IBS) is higher.
There should be no absolute correlation with eating late-night snacks.

Managing nighttime eating habits and understanding the associated stomach pain and digestive issues can be quite complex, especially when considering the interplay between diet, lifestyle, and individual health conditions. Based on the symptoms you've described, it seems that your body is reacting negatively to the changes in your eating patterns, particularly the cessation of nighttime eating.

Firstly, it's important to recognize that your gastrointestinal (GI) system thrives on routine. When you suddenly change your eating habits, such as cutting out late-night snacks, your body may respond with discomfort, including stomach pain and altered bowel habits. This is particularly true if you have a history of digestive issues, as you mentioned.


Understanding Your Symptoms
1. Stomach Pain and Digestive Discomfort: The pain you experience upon waking could be attributed to several factors. When you skip meals or snacks, your stomach may produce excess acid in anticipation of food, leading to irritation and discomfort. This can manifest as pain or a burning sensation, often referred to as "hunger pangs." Additionally, if your body is accustomed to regular food intake, sudden deprivation can lead to increased sensitivity and discomfort.

2. Changes in Bowel Movements: The shift in your bowel habits, such as experiencing softer stools or an increased urgency to use the bathroom, may be a response to dietary changes. Your gut microbiome, which is influenced by your diet, can react to the absence of certain foods, leading to changes in digestion and stool consistency. Furthermore, stress and anxiety, particularly related to your work or academic pressures, can exacerbate gastrointestinal symptoms, leading to conditions like irritable bowel syndrome (IBS).

3. The Role of Nighttime Eating: Eating at night can sometimes help stabilize your digestive system, especially if your body has adapted to that routine. If you find that eating a small, healthy snack before bed helps maintain regular bowel movements and reduces discomfort, it may be beneficial to incorporate this back into your routine. The key is to choose healthier options that are less likely to contribute to weight gain, such as fruits, yogurt, or whole grains.


Recommendations for Improvement
1. Gradual Dietary Adjustments: Instead of completely eliminating nighttime snacks, consider gradually reducing portion sizes or opting for healthier choices. This can help your body adjust without causing significant discomfort.

2. Regular Meal Patterns: Establish a consistent eating schedule throughout the day. Aim for balanced meals that include a mix of carbohydrates, proteins, and healthy fats. This can help regulate your digestive system and prevent the discomfort associated with hunger.

3. Hydration: Ensure you are drinking enough water throughout the day. Dehydration can contribute to digestive issues, including constipation and discomfort.

4. Stress Management: Since you mentioned that stress can trigger digestive issues, incorporating stress-reducing techniques such as mindfulness, yoga, or regular physical activity can be beneficial. These practices can help alleviate anxiety and improve overall gut health.

5. Consult a Healthcare Professional: Given your history of digestive issues and the persistent nature of your symptoms, it may be wise to consult with a gastroenterologist or a registered dietitian. They can provide personalized advice and may recommend tests to rule out any underlying conditions, such as food intolerances or gastrointestinal disorders.


Conclusion
In summary, your symptoms appear to be a result of both dietary changes and possibly stress-related factors. By gradually reintroducing healthy nighttime snacks, maintaining a regular eating schedule, and managing stress, you may find relief from your stomach pain and digestive discomfort. Remember, it's essential to listen to your body and seek professional guidance if symptoms persist or worsen. Your health and well-being should always be the priority, and finding a balance that works for you is key.
