Gastroesophageal Reflux Disease (GERD) is a common and long-lasting condition that affects many people around the world. 

It happens when stomach acid flows backwards into the esophagus, causing uncomfortable symptoms like heartburn, chest pain, and sometimes breathing problems.

While there are medicines to help, lots of people are trying changes in their diet to manage GERD symptoms more naturally.

One idea that’s getting attention is adding seaweed to the diet. Seaweed is packed with nutrients and has been linked to better health in many studies. 

It’s a common ingredient in many types of food and could help ease GERD symptoms.

In this blog post, we’ll talk about what causes GERD, signs and symptoms to watch for, the best types of seaweed to eat if you have GERD, and how seaweed might help with GERD. 

Plus, we’ll share some easy ways to add seaweed to your diet to help manage GERD symptoms.

What Causes Gerd: Signs & Symptoms

Causes of GERD:

1. Lower Esophageal Sphincter (LES) Dysfunction : When the Lower Esophageal Sphincter (LES) isn’t working properly, it means there’s a problem with a muscle ring that acts like a valve between your throat and stomach. 

Normally, it keeps stomach acid where it belongs – in your stomach. But if it gets weak or too relaxed, that acid can come back up into your throat, causing the symptoms of GERD.

2. Hiatal hernia: A hiatal hernia happens when the upper part of your stomach pushes up through an opening in your diaphragm into your chest area. 

This shift can make the Lower Esophageal Sphincter (LES) weaker and lead to acid reflux.

3. Obesity: Carrying extra weight can push on your stomach, squeezing it and causing stomach acid to move up into your esophagus. This can make GERD symptoms worse.

4. Pregnancy: When you’re pregnant, hormones can make the muscle valve between your esophagus and stomach (LES) relax more than usual. 

This can lead to more acid reflux.

5. Certain Foods and Beverages: Spicy foods, citrus fruits, tomatoes, chocolate, caffeine, and alcohol can all bother your LES or irritate your esophagus, making GERD symptoms flare up.

6. Smoking: Smoking weakens the muscle valve between your esophagus and stomach, making it easier for stomach acid to flow back up. This can raise your chances of having GERD.

7. Certain Medications: Some medicines like NSAIDs (like ibuprofen), calcium channel blockers, and certain asthma drugs can make GERD worse by either relaxing the muscle valve or irritating the lining of your esophagus.

Signs and Symptoms of GERD:

1. Heartburn: This feels like a burning sensation in your chest, especially after you eat or when you’re lying down. It’s one of the most common signs of GERD.

2. Regurgitation: Sometimes, acidic fluid or food can come back up into your throat or mouth, giving you a sour taste. This is called regurgitation.

3. Difficulty Swallowing (Dysphagia): GERD can make your esophagus narrow, making it hard to swallow solid foods.

4. Chronic Cough: If you have GERD, you might find yourself coughing a lot, especially at night or after meals. This happens because stomach acid irritates your throat and airways.

5. Hoarseness or Sore Throat: Acid reflux can make your vocal cords swollen and sore, leading to a hoarse voice or a throat that always feels scratchy.

6. Chest Pain: Sometimes, GERD can cause chest pain that feels a lot like a heart attack, especially after eating or when you’re being active.

7. Respiratory Symptoms: People with GERD might experience wheezing, asthma attacks, or even pneumonia more often. 

That’s because stomach acid can sneak into the lungs and airways, causing breathing problems.

Best Seaweed For GERD


1. Nori (Porphyra spp.)

Nori is most commonly recognized as the wrapping for sushi rolls, but it offers more than just aesthetics. 

Packed with essential nutrients like B vitamins, including the crucial B12 for nerve health and energy, nori contributes to overall well-being.

Its dietary fibre content not only supports digestion but also potentially helps stave off acid reflux episodes. 

With its mild taste and thin texture, nori is an effortless addition to a range of dishes suitable for those with GERD.

2. Wakame (Undaria Spp.)

With its gentle flavour, wakame brings more to the table than just taste.

It’s rich in fucoxanthin, a carotenoid with antioxidant properties that may ease esophageal irritation through anti-inflammatory effects.

The soluble fibre in wakame aids in maintaining gut health by promoting regular bowel movements and preventing constipation, a factor that can worsen GERD symptoms.

3. Arame

Arame, resembling fine hair and boasting a nutty flavour, is a decent source of dietary fibre.

While there’s limited research on its direct impact on GERD, arame may aid digestion and potentially alleviate reflux symptoms.

4. Kombu (Laminaria Spp.)

Kombu, a variety of kelp, stands out for its fibre content, particularly alginate. 

Alginate is known for its ability to form a protective barrier in the stomach, reducing the backward flow of stomach acid into the esophagus.

Moreover, kombu provides essential minerals like potassium and magnesium, crucial for maintaining electrolyte balance and promoting optimal digestive function.

5. Mozuku

Native to Japan and Okinawa, mozuku is a dark brown, hair-like seaweed packed with minerals such as magnesium. 

These minerals may aid in relaxing the esophageal sphincter, potentially reducing instances of acid reflux.

If you’re considering eating seaweed to ease GERD, choose types that are mild and easy on your stomach. 

Be careful not to eat too much and avoid spicy or strongly seasoned seaweed dishes, as they can make GERD symptoms worse. 

Before changing your diet, talk to your doctor or a healthcare professional. They can give you advice that fits your health needs.

Seaweed Supplements For GERD

1. Alginates

Alginates found in seaweed are known for their ability to create a protective shield in the stomach. 

This shield acts as a barrier, stopping stomach acid from moving back up into the esophagus, which can decrease the frequency of acid reflux.

2. Minerals

Seaweed provides important minerals like potassium, magnesium, and calcium, which are essential for a healthy digestive system. 

These minerals can help control the production of stomach acid and support overall gut health.

3. Fiber

Seaweed is also packed with dietary fiber, which promotes regular bowel movements and prevents constipation. 

Since constipation can make GERD symptoms worse, adding seaweed to your diet might help keep your digestive system healthy and reduce the chances of symptom flare-ups.

4. Antioxidants

Some types of seaweed contain antioxidants such as fucoxanthin, which have anti-inflammatory properties. 

These antioxidants can help reduce inflammation in the esophagus caused by acid reflux, which may ease the discomfort of GERD.

Before you start taking seaweed supplements to help with GERD, it’s crucial to talk to a healthcare provider. 

They can give you advice that’s tailored to your specific health situation and make sure the supplements are safe for you. 

Also, make sure to pick supplements from trusted brands to ensure they’re effective and safe for you.

How Seaweed Can Help With GERD?

Seaweed offers potential benefits for individuals suffering from GERD through various mechanisms:

1. Alginates

Seaweed contains alginates, compounds that can create a protective barrier in the stomach.

This barrier acts as a shield against stomach acid, reducing the likelihood of acid reflux episodes by preventing acid from backing up into the esophagus.

2. Anti-inflammatory Properties

Some seaweed types possess antioxidants and anti-inflammatory agents. 

These components may help alleviate the inflammation in the esophagus triggered by acid reflux, thereby easing the discomfort associated with GERD.

3. Nutrient-rich 

Seaweed is packed with essential vitamins, minerals, and fiber crucial for maintaining digestive health. 

Incorporating seaweed into one’s diet as part of a balanced nutritional plan can foster proper digestion and potentially alleviate GERD symptoms.

4. Digestive Support

The fiber content in seaweed aids in promoting regular bowel movements and preventing constipation, a factor that can aggravate GERD symptoms by supporting healthy digestion.

5. Low Acidity

Specific seaweed varieties like nori and wakame have low acidity levels, making them stomach-friendly and suitable for individuals dealing with GERD.

Adding seaweed to what you eat might help with GERD symptoms naturally. 

But it’s important to pick kinds of seaweed that won’t upset your stomach, and avoid dishes with lots of spices that might make acid reflux worse. 

Before you make big changes to what you eat, it’s smart to talk to a doctor first, especially if you have other health issues or take medicine.

Ways to Include Seaweed in Your Diet for GERD

Here are easy ways to add seaweed to your meals if you have GERD:

1. Seaweed Salad: Make a tasty seaweed salad by mixing cooked seaweed with cucumber, sesame seeds, and a light dressing. It’s yummy and full of good stuff for your body.

2. Sushi Rolls: Try sushi rolls with seaweed, also called nori. Fill them with avocado, cucumber, and cooked fish or tofu for a meal that’s easy on your stomach.

3. Miso Soup: Put strips of dried seaweed, like kombu or wakame, in homemade miso soup. It gives the soup extra flavour and nutrients without feeling heavy.

4. Seaweed Snacks: Get crispy roasted seaweed snacks at the store. They’re lightly seasoned and perfect for munching on their own or with a little bit of rice.

5. Stir-fries and Soups: Add dried seaweed strips to stir-fries or soups for more taste and texture. Seaweed goes well with veggies, tofu, and lean meats like chicken or shrimp.

6. Seaweed Wraps: Use sheets of nori instead of regular bread or tortillas to wrap sandwiches. Fill them with lean proteins and veggies for a healthy meal that’s good for GERD.

7. Seaweed Seasoning: Sprinkle powdered seaweed seasoning, like furikake, on rice, salads, or roasted veggies for extra flavour. It’s tasty and adds more nutrients to your food.

Remember to start with small amounts of seaweed if you’re not used to eating it and see how your body feels. 

If you have any problems or your GERD symptoms get worse, talk to a doctor for advice.

Alternative Ways To Treat GERD

There are other ways you can try to feel better from GERD besides the usual medicine. Here are some ideas:

1. Change Your Diet

Switching up what you eat might help ease GERD symptoms. Stay away from foods that make it worse, like spicy, acidic, and fatty foods, as well as coffee, alcohol, and chocolate. Instead, eat smaller meals more often and focus on whole, natural foods.

2. Change Your Lifestyle

Changing how you live can also help with GERD. Keep a healthy weight, don’t lie down right after eating, raise the head of your bed when you sleep and wear loose clothes so your stomach doesn’t feel squished.

3. Try Natural Remedies

Certain herbs and supplements like ginger, liquorice root, slippery elm, and chamomile might help soothe GERD symptoms. You can have them as teas, or supplements, or add them to your food.

4. Acupuncture

Some people find relief from GERD through acupuncture, a practice from China where tiny needles are put into specific points on your body. 

It’s believed to help balance your body’s energy and make you feel better.

5. Yoga and Meditation

Doing yoga or meditation can help lower stress, which can make GERD worse. Some yoga poses and breathing exercises might also help your digestion and make you feel less uncomfortable.

6. Chiropractic Care

For some, getting adjustments from a chiropractor can help with GERD symptoms, especially if spine problems are affecting how your nerves work and causing digestion issues.

7. Aromatherapy

Using certain essential oils like peppermint, lemon, or lavender might calm down tummy troubles from GERD. You can breathe them in, rub them on your skin, or use them in a diffuser.

But, before you try any of these things, it’s important to talk to your doctor, especially if you’re already taking medicine or have other health problems. 

They can help you figure out the best plan for you and make sure it won’t interfere with your other treatments.


In summary, adding seaweed to your diet can be a tasty and helpful way to naturally deal with GERD symptoms. 

Opting for seaweed types that are high in alginates, antioxidants, and important minerals can promote a healthier digestive system and lessen the number of acid reflux episodes. 

When combined with lifestyle changes and other alternative treatments, seaweed provides a comprehensive approach to managing GERD, giving people the chance to feel better and enjoy a better quality of life.
