Can Eating Guava Cause Stomach Ulcers? Nutrition Tips for Weight Loss

Will eating guava cause stomach ulcers?

I have a question.
I am currently trying to lose weight.
I am 166 cm tall and weigh 52 kg.
For breakfast, I have been eating guava and Diet Coke every day for a long time.
Occasionally, I drink milk, but it makes me have diarrhea.
I heard that eating guava on an empty stomach is not good for the stomach.
I remember seeing news online about someone getting a stomach ulcer from eating guava.
Is that true? I also noticed that the guava seeds are not digested when I have a bowel movement; is that normal? Additionally, my hands tremble, and my face turns red without any movement.
Could this be due to a deficiency in some nutrients? When is the best time to take a multivitamin? Please answer me.
Thank you very much! ^^

Hello! Based on your height, your standard weight should be between 54 to 65 kg, so you are considered to be underweight and have not yet reached the standard weight range.
Why do you want to lose weight? A small guava contains about 60 calories, with its main nutritional components being carbohydrates and small amounts of vitamins, minerals, and fiber.
In contrast, a can of Diet Coke contains only 1 calorie.
If your breakfast consists solely of these two foods, and you have other foods for lunch and dinner (do you?), your nutritional status may be acceptable.
However, if your meals consist of only one or two items, you may be at risk for gastric ulcers and malnutrition due to a lack of a variety of nutrients.
In this case, taking a multivitamin may be necessary.
However, I encourage you to return to a normal, balanced diet that includes foods from all six major food groups.
This will help prevent symptoms such as trembling hands due to low blood sugar.
Please consult a nutritionist as soon as possible to help you adjust to a healthier diet.

More Info

Eating guava and its potential effects on stomach health, particularly in relation to stomach ulcers, is a topic that requires careful consideration. Guava is a nutritious fruit, rich in vitamins, particularly vitamin C, fiber, and antioxidants. However, consuming it in certain ways or in excess can lead to gastrointestinal discomfort for some individuals.

Can Eating Guava Cause Stomach Ulcers?
There is no direct evidence that eating guava causes stomach ulcers. Stomach ulcers, or peptic ulcers, are primarily caused by factors such as Helicobacter pylori infection, prolonged use of nonsteroidal anti-inflammatory drugs (NSAIDs), excessive alcohol consumption, and smoking. However, certain foods can exacerbate symptoms in individuals who already have ulcers or are prone to gastrointestinal issues.

Eating guava on an empty stomach may lead to discomfort for some people, as the high fiber content can be harsh on an empty digestive system. If you have a sensitive stomach or existing gastrointestinal issues, it may be wise to consume guava in moderation and not on an empty stomach.

Nutritional Tips for Weight Loss
Your current weight of 52 kg at a height of 166 cm gives you a Body Mass Index (BMI) of approximately 18.8, which is on the lower end of the healthy weight range. If your goal is to lose weight, it’s essential to do so in a healthy manner that does not compromise your nutritional intake or overall health.

1. Balanced Diet: Instead of relying heavily on guava and diet soda, consider incorporating a variety of fruits, vegetables, whole grains, lean proteins, and healthy fats into your diet. This will ensure you receive a balanced array of nutrients.

2. Avoid Excessive Sugar and Caffeine: Diet sodas, while low in calories, can lead to cravings for sweet foods and may not provide any nutritional value. Additionally, caffeine can irritate the stomach lining, especially if consumed in large amounts.

3. Regular Meals: Skipping meals or relying on a limited diet can lead to nutrient deficiencies. Aim for regular meals that include a balance of macronutrients (carbohydrates, proteins, and fats).

4. Hydration: Ensure you are drinking enough water throughout the day. Sometimes, feelings of hunger can be mistaken for thirst.

5. Monitor Fiber Intake: While fiber is essential for digestive health, too much fiber, especially from sources like guava seeds, can lead to digestive discomfort. If you notice undigested seeds in your stool, it may indicate that your body is having difficulty digesting them. Consider blending guava into smoothies or cooking it to make it easier on your digestive system.

Nutritional Deficiencies and Symptoms
The symptoms you describe, such as hand tremors and facial flushing, could be indicative of several issues, including potential nutritional deficiencies. Common deficiencies that can cause such symptoms include:
- Vitamin B12: Important for nerve function and energy production. A deficiency can lead to neurological symptoms.

- Magnesium: Low levels can cause muscle tremors and spasms.

- Iron: Deficiency can lead to fatigue and weakness.

Taking a multivitamin can be beneficial, but timing can matter. It’s generally best to take multivitamins with food to enhance absorption and reduce the risk of stomach upset.

Conclusion
In summary, while guava is not likely to cause stomach ulcers, consuming it in moderation and as part of a balanced diet is advisable. Focus on a varied diet that meets your nutritional needs while supporting your weight loss goals. If you continue to experience gastrointestinal discomfort or other concerning symptoms, it would be wise to consult with a healthcare professional or a registered dietitian for personalized advice and support.
