Hippocrates once said, “Let food be thy medicine and medicine be thy food.”

Medicines are drugs used for the treatment or prevention of disease. When we take the drug, there is risk of drug-nutrient interaction. People who are at risk are:

  • Those who have a poor diet
  • Those who have serious health problems
  • Growing children
  • Pregnant women
  • Older adults
  • Patients taking two or more medications at the same time
  • Those using prescription and over-the-counter medications together at the same time
  • Patients not following medication directions
  • Patients taking medications for long periods of time
  • Those who drink alcohol or smoke excessively

As per the best sports nutritionist in Mumbai, all the processes of medicines i.e pharmacodynamics & pharmacokinetics take place in the gut. So the first line of connection for medicine to enter into cells is through gut organs. If you are taking any medicine definitely leads to altering the mechanism happening in the gut responsible for the issue creation.

Our digestive system can be affected by medicines n a number of different ways.

Let us have a look at some drugs of the GUT.


 Class of drugExampleEffectSide effctes


Aluminum, calcium, or magnesium  bound to carbonate or phosphate


It  Buffers gastric acid


•         Constipation

•         aluminum-intoxication

•         osteomalacia

•         hypophosphatemia.





It  lowers surface tension of gas bubbles


•         Nausea

•         Constipation

•         Diarrhea

•         Headache



•         Acarbose


They delays carbohydrate digestion by inhibiting alpha-glycoside hydrolase, which interferes with conversion of starch to monosaccharides


•         Diarrhea,

•         Gas,

•         Bloating,

•         Upset stomach,




•         Octreotide (somatostatin analog)

•         Somatostatin



They inhibits release of insulin and other gut hormones; slows rate of gastric emptying and small intestine transit time; and increases intestinal water and sodium absorption•         Abdominal Pain

•         Flatulence

•         Constipation

•         Vomiting

•         Fatigue

5.•         H2 blocker



•         Cimetidine

•         Ranitidine

•         Famotidine

•         Nizatidine

They blocks the action of histamine on parietal cells, decreasing the production of acid


•         Diarrohea

•         Dizziness

•         Headache


6.•         Proton pump inhibitor (PPI)



•         Omeprazole

•         LansoprazoleE

•         Someprazole

•         Pantoprazole

•         Dexlansoprazole

•         Rabeprazole


They inhibits acid secretion


1.       Nausea

2.      Vomiting

3.      Headache

4.      Diarrohea




•         Metoclopramide

•         Erythromycin

•         Domperidone


It Increases contractility of the stomach and shortens the gastric emptying time.







8For Constipation (Stool Softener)


•         Docusate sodium


They are anionic surfactants with an emulsifying detergent-like property that increases the water content in stool to make bowel movements easier to pass


•         Stomach Pain

•         Diarrohea


9.For Constipation (Osmotic agents )


•     Magnesium hydroxide

•         Sorbitol

•         Lactulose

•         polyethylene glycol

They contain poorly absorbed or nonabsorbable sugars and work by pulling fluid into the intestinal lumen


•         Loss of potassium

•         Headache

•         Nausea

•         Backache


10.For Constipation (Stimulant laxatives )


•Bisacodyl and senna


They increase peristaltic contraction and bowel motility and act to prevent water absorption. Chronic use of laxatives is associated with abdominal cramping and fluid imbalance.


•         Faintness

•         Muscle aches

•         Fatigue

•         Skin rash



• Antiinflammatory agents (aminosalicylates)

•         Immunosuppressive agents (cyclosporine, azathioprine, mercaptopurine),

•         Antibiotics (ciprofloxacin and metronidazole)

•         Monoclonal tumor necrosis factor antagonists (anti-TNF), and infliximab, adalimumab, certolizumab, and natalizumab


They inactivate one of the primary inflammatory cytokinesDisturb gut micbiome



Studies have shown that exercise and nutrition can often outperform drugs in achieving health goals. Most importantly, they do it without any of the side effects with which prescription drugs are often riddled.

Specific diets are used for Nutrition Therapy as it becomes a  therapeutic approach to treat medical conditions and their associated symptoms

Definitely food cannot replace medication entirely, a healthy diet is a foundation to reduce the usage and long term side effect

Conclusion on why nutrition therapy is a better choice rather than medicine.

  • What we eat is the main culprit behind chronic diseases, hence eating a healthier diet helps prevent and treat the most common conditions.
  • We can see various side effects of medicines on the gut and other organs of body as medicines suppress any of natural mechanism happening in gut
  • Proper nutrition intake are the natural method to combat any issue.
  • In each gut ailment we can see, absence of some nutrients or presence of excessive amount respionsible for the issue.
  • They hinder gut microbiome and increase the risk of gut health
  • They provide long term effect on gut issues and will help to control to happen in future.


Nutrition therapy can be long term of treatment for many GI orders. Some of the common Medical Nutrition Therapy for some common diseases are

  • Anorexia -Small, frequent meals may help to maximize intake in patients who have anorexia. Avoiding high-fat foods may lessen the feeling of fullness.
  • Peptic ulcer: High protein diet, Avoid chilli, spices.
  • Flatulence, Bloating: Avoid food which lead to gas production like cauliflower, broccoli, beans.
  • Nausea and vomiting – Easily digested carbohydrate foods, such as crackers, toast, oatmeal, and bland fruit, low-fat usually are well tolerated. Avoid liquids with meals as liquids can promote the feeling of fullness hence lead to lower intake of food.
  • GERD– Lose weight if overweight, avoid large meals and bedtime snacks, eliminate individual intolerances, and avoid alcohol, caffeine, decaffeinated coffee, chocolate, fatty foods, peppermint and spearmint flavors, and cigarette smoke.
  • Constipation –High fibre diet which includes cellulose, hemicellulose, pectins, gums, lignins, starchy materials, and oligosaccharides and proper water intake along with inositol, B Glucan rich food will help.
  • Diarrohea -Modest intake of prebiotic components and soluble fibers such as pectin or gum slows transit through the GI tract.
  • Irritable Bowel syndrome – Probiotic and prebiotic rich foods, Low FODMOP Diet
  • Celiac Disease – Avoid gluten free food slike sweet potato, topiaco, corn, millets, quinoa, rice.

“Irrespective of the side effects, medicines are chosen over diet. Do you know why? Because eating well and maintaining healthy habits is hard infact very hard.”
