Heartburn is usually described as pain in the chest. This normally happens when stomach acid flows back up into the oesophagus (acid reflux) hence causing a burning sensation – that is usually around the chest or where the heart is. Since stomach acid is causing the burning sensation, heartburn is commonly associated with hyperacidity. To repeat, heartburn is the physical pain one feels in the chest area when stomach acid is flowing back up into the oesophagus. 


acid reflux

When one suffers heartburn, it is common to say Acid reflux is happening. Acid reflux is the actual physical flow of stomach acid back into the oesophagus. This is what causes one to feel heartburn. 



Gastroesophageal Reflux Disease

GERD is basically Heartburn and Acid Reflux that occur regularly; usually at least twice a week, or in some cases, even as little as once a week.  According to the Clinical Practice Guidelines on the Diagnosis and Treatment of GERD 2014,


Heartburn and acid regurgitation are often considered the typical symptoms of GERD and an office diagnosis of GERD may be made when these are present. 

A clinical diagnosis of GERD can already be made even without an endoscopy. As long as typical symptoms such as heartburn and acid reflux is present. However, GERD can also be mistaken for heart attacks or other complications and diseases. Hence, It is very important to consult a doctor if one is unsure about their symptoms. 

So now that we have a better understanding of how Heartburn, Acid Reflux, and GERD are all inter-related, what are their typical symptoms?


A burning pain in the chest that usually occurs after eating and may occur at night

are very similar to the triggers of hyperacidity

Spicy or fatty food

Skipping meals or irregular eating habits

Fasting or starving

Alcoholic drinks and smoking

Caffeine, softdrinks or acidic beverages


Pregnant women are more prone to suffering heartburn or acid reflux



Similar to Hyperacidity, Avoiding triggers over long-term will help prevent heartburn/acid-reflux/GERD. However, OTC solutions can help relieve heartburn and its symptoms. Antacids are a common solution because they neutralize the acidity of the stomach quickly. However, since heartburn is more complex and usually lasts longer, we offer a solution that is fast, but also long lasting. By combining an antacid with an H2 Blocker, Kremil-S Advance helps supress production of stomach acid for longer periods of time in order to provide better relief from heartburn. 




Pregnant Women are more likely to suffer symptoms of Heartburn, acid reflux, and GERD because the hormonal changes sometimes allow the oesophageal muscles to relax and allow acid to flow back up. Common tips to alleviate heartburn such as propping one’s head up/avoid sleeping sideways, and also avoiding heavy meals at night will help. On top of this H2 Blockers such as Kremil-S Advance (link) have been studied extensively and has a well-established efficacy and safety in pregnancy. However, it is always best to check with your doctor before taking this medicine.
