Do you sometimes feel a burning sensation in your chest and a sour taste in your throat when you eat a spicy meal at night? Or do you feel like your throat hurts when you wake up in the morning, and your voice changes? Many of us call this "gastritis." That's not entirely wrong, but this condition can be a little different. Medically, we call this GERD, which means (Gastroesophageal Reflux Disease). Today we are going to talk about a special medicine made from seaweed that helps with this GERD condition, but which many people in our country do not know about. That is alginates.
Simply put, what is GERD?
This is very easy to understand. Imagine, inside our stomach there is a strong acid that helps digest the food we eat. This acid should only be inside the stomach. The stomach is designed to withstand this acid. But the tube through which the food we eat goes, the esophagus, cannot withstand this acid.
Normally, there is a muscular ring between the stomach and the esophagus, like a door. When we swallow food, this door opens and then closes tightly. This stops the acid in the stomach from coming up. However, in someone with GERD, this door may not close properly. Then the acid in the stomach comes up, that is, into the esophagus. That is when we get symptoms like heartburn , pain in the middle of the chest, and a sour taste in the throat. When the acid comes up like this for a long time, the walls of the esophagus can also be damaged.
Many people refer to "gastritis" as inflammation of the stomach. However, GERD is a condition caused by stomach acid flowing back up. Although the symptoms of the two are similar, the causes and treatments may be different.
So what are these alginates? How do they work?
This is the most important part of this article. Alginates are a natural compound found in seaweed. But don't just eat seaweed! They are purified and refined to make medicine.
The way alginates work is amazing. When we take this medicine, it goes into the stomach and combines with the acid there, forming a gel-like, or foam-like, layer that floats on top. Think of it like a layer of oil floating on top of a bottle full of water. We call this gel layer a "raft."
This "raft" is very light, so it floats on top of the other things in the stomach. But it's strong enough to stop the acid in the stomach from coming up into the esophagus. Simply put, it creates a physical barrier . That is, it creates a kind of lid between the stomach and the esophagus. This prevents the acid from coming up.
What are the benefits and risks of alginates?
Like any medicine, alginates can have benefits and some risks. Let's take a look at them.
| Benefits | Risks & Downsides |
|---|---|
| Fast-acting: The medicine starts working almost immediately after taking it. You can take it with or after food. | It may not work for everyone: This may not provide any relief from some people's symptoms. |
| Safety: These are generally considered safe for pregnant women, nursing mothers, and even children (but be sure to consult your doctor before taking them ). | Side effects: Rarely, side effects such as bloating or constipation may occur. |
| Ease of availability: These can be purchased over-the-counter at a pharmacy without a doctor's prescription. | Interactions with other medications: If you are taking medications for other conditions, these may affect the effectiveness of those medications. |
Special situations in which this medicine should not be used
Although alginates are very effective for GERD symptoms, they don't work for all conditions. Keep these things in mind, especially.
- If the esophagus is damaged: When you have GERD for a long time, the walls of the esophagus can become burned and damaged by acid. We call this (esophageal erosions) or (ulcers). This type of condition cannot be treated with alginates. It requires other stronger medications prescribed by a doctor.
- Barrett's esophagus: This is a more complicated condition that can be caused by GERD. It involves changes in the cells of the esophagus. Alginates are also not suitable for this condition.
- Kidney Disease: This is very important. If you have kidney disease, you should definitely talk to your doctor before taking alginates. Some alginates contain sodium. It is not advisable for kidney patients to consume too much sodium.
What is the difference between alginates and the antacids we all know?
Many people use antacids for heartburn. For example, things like Digene and Gelusil. So are alginates the same thing? No. These two work in two completely different ways.
| Characteristic | Alginates | Antacids |
|---|---|---|
| How it works | It creates a physical barrier (raft) over the stomach acid, stopping the acid from coming up. | It chemically neutralizes the acid in the stomach. That is, it makes the acid less strong. |
| Main objective | Stopping acid reflux. | Reducing the strength of the acid already in the stomach. |
| Examples | It is mainly contained in products like Gaviscon Advance. | Liquids and tablets like Digene and Gelusil. |
But this should also be said. There are some medications that are made by combining both alginates and antacids. Some products, like Gaviscon, contain both of these compounds. This provides both benefits.
How effective is this medicine? Compared to other medicines
Research has found that alginates are a more effective way to control common GERD symptoms than antacids .
However, there are other medications that doctors often prescribe for GERD. You may have heard of these names: Omeprazole, Esomeprazole, Pantoprazole. These belong to a group called PPIs (Proton Pump Inhibitors) . Also, drugs like Famotidine belong to a group called H2RAs (Histamine-2 Receptor Antagonists) . These medications work by reducing the production of acid in the stomach.
According to research, alginates are a slightly less effective drug than PPIs and H2RAs. But the advantage of alginates is that they work immediately after taking them and are much safer.
Therefore, your doctor may assess your condition and perhaps give you an alginate to take as needed, along with a PPI.
Things to consider before I take this medicine
Now that you have a good idea about alginates, keep these things in mind if you are considering using this medicine.
1. See your doctor first: Although this is available over-the-counter, it's important to know for sure whether your heartburn is actually GERD or something else. Only your doctor can tell you if it will work with your health history and other medications you're taking.
2. Tell your doctor about all other medications you take: If you are taking medication for diabetes, blood pressure, heart disease, or anything else, tell your doctor about it.
3. Use correctly: These come in liquid, chewable, and powder forms. Take them exactly as your doctor tells you, in the dose, and at the exact time. They are usually taken after meals.
You might not have thought that a compound found in seaweed could solve your heartburn problem. Alginates are a safe, effective, and quick-relief option for many people suffering from GERD symptoms. But remember, it's always wise to seek medical advice before self-medicating.
Take-Home Message
- Alginates are a medicine made from seaweed and used to treat GERD symptoms.
- This creates a protective gel layer (raft) that floats on top of stomach acid, preventing the acid from reaching the throat.
- This does not neutralize acid like antacids. It acts as a physical barrier.
- This works quickly and is generally safe, even for pregnant mothers. But always take only on medical advice.
- People with kidney disease and those taking other medications should definitely inform their doctor before taking this.
- Let your doctor accurately diagnose the cause of your chest pain and determine the best treatment for you.
