Hi there, 👋 First – nothing to be embarrassed about. You’re being smart by asking for help. Let’s break this down.
· 🧠 You likely do NOT have lactose intolerance – because avoiding milk didn’t help. That’s a big clue. · 🎯 Most probable cause in a 15‑year‑old: Irritable Bowel Syndrome (IBS) – causes random lower left pain, bloating, and changes in gas. It’s very common in teens and not dangerous. · 💨 About the smell fear: Bloating/gas with IBS rarely has a strong odor unless you eat specific triggers (onion, garlic, beans). You’re likely not smelling as much as you think. · 🚫 Don’t cut fiber completely – that can worsen IBS. Try soluble fiber (oatmeal, bananas, rice) instead of rough fiber (raw veggies, bran). · 📓 Start a 1‑week diary: Write down food, stress, sleep, and symptoms. Look for patterns that aren’t just milk. · 🩺 See a pediatrician or a GI doctor – they can rule out celiac disease, constipation, or pelvic issues. No need for tests unless symptoms worsen. · 🧘 Stress makes it worse – school anxiety can directly trigger IBS. Deep breathing before class helps.
What to do now:
1. Eat small, regular meals. 2. Try a low‑FODMAP diet (ask your mom to help look it up). 3. Don’t be afraid to talk to your school nurse – they’ve heard everything.
You are normal. This is fixable. Go see a doctor for peace of mind.

Ongoing gas with mild left-sided pain in teens is commonly due to functional gut issues like Irritable Bowel Syndrome or food intolerances (not always just lactose), rather than something dangerous. Try simple steps first—eat slowly, avoid fizzy drinks and chewing gum, keep a food/symptom diary, and consider a low-FODMAP style diet—but don’t overly restrict fiber without guidance. Please see a pediatrician or gastroenterologist for proper evaluation (they may check for Irritable Bowel Syndrome, intolerances, or rarely Celiac Disease) so you can get treatment and feel confident at school.
Hello
For a 15-year-old girl with long-term mild stomach pain in the lower left side and occasional bloating, the most common causes are functional bowel issues such as gas buildup, mild constipation, or irritable bowel syndrome, rather than true lactose intolerance—especially since symptoms continued even after stopping milk. Hormonal changes during adolescence, anxiety about school or embarrassment about odor, and irregular eating or bathroom habits can also contribute.
What to do now: keep a simple food and symptom diary for two to three weeks, eat regular meals, drink enough water, and avoid holding in gas or stool at school. Gentle daily movement and not skipping breakfast often helps bowel rhythm. If milk seems suspicious, you can try lactose-free milk or yogurt rather than removing all dairy, because many teens tolerate small amounts.
Over-the-counter options like simethicone for gas or a mild probiotic can be considered after discussing with a parent or pharmacist.
Medical review is important if the pain has lasted four years, even if mild. A doctor may check for constipation, food intolerance, or less common causes such as inflammatory bowel conditions. Seek evaluation sooner if there is weight loss, blood in stool, frequent diarrhea, vomiting, fever, pain waking her from sleep, or worsening pain.
The key reassurance is that this pattern is very common in teenagers and is usually manageable once the exact trigger—often bowel habits or gas—is identified.
Hello dear See confirm of Lactose tolerance is must Iam suggesting some tests for confirmation Please share the result with general physician medicine for better clarity and for safety please donot take any medication without consulting the concerned physician Hydrogen breath test Blood lactose test Genetic test Stool acidity Rbs Esr CBC In addition you may get replacement with following products Yoghurt Tofu Khoya Lassi Curd Cheese Hopefully you recover soon Regards
What you’re describing—long-term gas, occasional lower abdominal pain (especially on the left side), and worry about odor—most closely fits a functional gut issue like Irritable Bowel Syndrome or chronic gas/bloating, which is very common in teenagers and not something to feel embarrassed about. The fact that it has been going on for years, doesn’t have clear food triggers, and didn’t improve much with removing milk or changing fiber suggests your gut may be sensitive rather than diseased. Gas can build up due to swallowing air, gut bacteria fermentation, irregular eating patterns, or stress—even if you don’t notice it directly—and this can cause both bloating and that random pain you feel.
The best way to manage this is not extreme restriction but balanced habits: eat regularly (don’t skip meals), avoid fizzy drinks and chewing gum, eat slowly, and keep a simple food diary to spot subtle triggers (like beans, fried foods, or processed snacks). You can also try probiotics for a few weeks and gentle physical activity (walking helps gas move). For school confidence, wearing breathable clothing and using the restroom when needed can help reduce anxiety about smell.
Most importantly, this is treatable and manageable, but since it has lasted years, it would be a good idea to see a doctor once to rule out things like food intolerance or gut imbalance and get proper guidance. Seek care sooner if you ever notice red flags like weight loss, blood in stool, severe pain, or persistent diarrhea/constipation. Overall, your situation is very common and not dangerous—you just need the right approach rather than cutting out random foods.
First, it’s important to note that digestive issues like bloating and stomach pain can have various causes, and lactose intolerance is just one possibility. Given that you’ve seen no improvement cutting out dairy and high-fiber foods, it’s worthwhile considering other potential causes. Keeping a food diary is a practical step here: track what you eat and when symptoms occur to see if there’s a pattern that might reveal a food sensitivity. It’s possible that something other than lactose is the trigger. Also, try managing stress, as this can impact gut health. If stress or anxiety seems to worsen the symptoms, incorporating relaxation techniques could help. Drink plenty of fluids and stay active, as both can aid in digestion. Probiotics might also be beneficial by balancing gut bacteria, so consider foods like yogurt (if tolerated) or supplements. If these steps don’t help, or symptoms worsen, consulting with a healthcare provider is the next step; they can rule out conditions like irritable bowel syndrome or small intestinal bacterial overgrowth, both of which could explain persistent symptoms. They may recommend tests or referrals such as a lactase deficiency test or even an elimination diet under supervision. Ensuring you see a doctor is crucial for any worsening pain, especially if it’s sharp, severely limiting your activities or accompanied by red flag symptoms like weight loss, fever, or blood in stools, as these require immediate attention.
Hello, thank you for sharing your concern. First of all, try not to feel embarrassed, this is very common. Many girls go through similar symptoms. The good thing is, it’s usually not serious and manageable once we understand the cause. Based on your symptoms, you might be having Irritable Bowel Syndrome or Food Intolerance or Gas-related discomfort, etc. Here is my advise-
1. Don’t overly restrict your diet- Cutting too many foods (milk, fiber, etc.) can actually make things worse. Instead: Eat a balanced diet, Avoid very oily, spicy, and junk food, Eat slowly and chew properly.
2. Drink enough water daily. Regular physical activity (even walking helps gas movement). Don’t hold in gas or stool.
3. Keep a small note of: What you eat, When symptoms happen. Sometimes triggers are subtle (like packaged food, cold drinks, etc.).
4. For gas and bloating relief, You can start this prescription- - Tab. Simethicone 40mg twice daily × 7 days. - Tab/Cap. Probiotic after meals × 14 days.
Please physically consult a doctor if you have: Weight loss, Blood in stool, Severe or worsening pain, Persistent diarrhea or constipation.
Your fear about smell or embarrassment is understandable, but Occasional gas is normal for everyone. With the right habits, this can be well controlled. This is likely a common, manageable gut sensitivity issue, not something dangerous. Focus on routine, diet balance, and stress control, and things usually improve gradually.
