Hello. Please stop drinking the energy drinks immediately. Consuming high-caffeine beverages like Sting and Red Bull regularly for two months has likely severely irritated your stomach lining, leading to a condition resembling acute gastritis.
Caffeine is a heavy gut stimulant that drastically increases acid production and speeds up bowel movements, which explains the sharp pain and diarrhea. Furthermore, large amounts of caffeine trigger a heavy adrenaline surge in the body, which is almost certainly the root cause of your sudden anxiety.
Meftal Spas is an antispasmodic and an NSAID (painkiller). It is not working because it does not stop stomach acid production, and worse, the mefenamic acid component in it can actually further irritate an already inflamed stomach lining. Continuing it might make your stomach pain worse. Your symptoms could also point toward other possibilities, such as a localized stomach ulcer from the chronic irritation, a secondary food-borne intestinal infection, or a caffeine-induced flare-up of irritable bowel syndrome (IBS). You need an acid-suppressing medication rather than a simple painkiller, but please consult a physician in person to get a proper prescription.
Next Steps
1.Visit a general physician or gastroenterologist for a physical checkup.
2.Ask the doctor if you need an antacid or a proton pump inhibitor (PPI) to heal the stomach lining.
3.Keep a close eye on your stools to ensure there is no hidden blood or dark discoloration.
4.If the diarrhea persists for more than a couple of days, get a routine stool test done to check for any underlying infection.
Health Tips
1.Make sure to double-check the physical labels of any medication you take to confirm dosages and check for warnings regarding stomach irritation.
2.Stick to a strictly bland, soft diet for the next few days—think curd rice, bananas, porridge, and plain coconut water to soothe the gut.
3.Drink plenty of water with ORS (Oral Rehydration Salts) throughout the day to replace the fluids lost from diarrhea and prevent dehydration.
4.If you notice black tarry stools, vomit that looks like coffee grounds, or if the stomach pain becomes suddenly unbearable, go to an emergency room immediately.
