Slow digestion: causes, symptoms and treatment

Slow digestion, sometimes described as heavy digestion, is a common discomfort that happens when food takes longer than usual to move through the digestive system. This can lead to unpleasant effects that interfere with daily life. It should not be confused with overeating discomfort or ordinary indigestion. In today's post, we explain the difference and look at the causes, symptoms and treatment of slow digestion.

What makes slow digestion different?

If we look at the main difference between slow digestion and overeating discomfort, we need to focus on both intensity and cause. Overeating discomfort is usually acute and temporary, often caused by eating too much, eating heavy foods or eating too quickly. Slow digestion, on the other hand, is more of a functional heaviness that appears after a meal even without overeating, and tends to recur due to functional causes.

Causes of slow digestion

If you are wondering what causes slow digestion or very slow digestion, there are several possibilities, but the most common are:

• The type of foods eaten: diets rich in ultra-processed foods can be harmful to the digestive system because of their high content of saturated fat, sugar, additives and salt, as well as the consumption of fizzy drinks, caffeine and alcohol.
• Eating too quickly, which can lead to gas because of swallowed air.
• Doing physical activity immediately after eating.
• Stress: it can slow digestion by altering nervous system signals.
• Age: over time, the production of digestive enzymes decreases.
• Pregnancy.
• Certain conditions or medications.

What are the symptoms of slow digestion?

The symptoms of slow digestion vary and may appear together or separately. They can include:

• A feeling of gastric fullness that is not directly related to the amount of food eaten.
• Discomfort such as pain, burning or bloating.
• Reflux.

• Gas.
• Nausea.
• Constipation or diarrhoea.

I have slow digestion. What should I do?

Dietary changes are the main remedy for heavy, slow digestion. With a few simple changes to your eating habits, you may notice a significant improvement, although sometimes there may be another cause behind it. Some useful tips include:

• Following a healthy, balanced diet, prioritising fruit, vegetables, whole grains, lean meat and fish, and healthy fats such as olive oil.
• Chewing properly and eating slowly.
• Reducing ultra-processed foods and foods high in sugar, salt and saturated fats.
• Taking fermented dairy products that help support a healthy gut flora, such as natural yoghurt or kefir.

Alongside these habits, you can also introduce supplements that may support the digestive process, such as:

• Bonusan Gastrozym capsules: they support proper digestion thanks to their supply of digestive enzymes.
• Forte Pharma Detox 5: an ideal formula to help the body cleanse itself and improve digestive wellbeing, thanks to its high concentration of plant-based actives such as artichoke, lemon juice, birch, chlorella, rosemary and burdock.
• Pranarôm Digest Confort tablets: they contain peppermint and ginger essential oils that help promote digestive comfort.
• Aboca NeoBianacid chewable tablets: they provide a protective effect by helping shield the mucosa and relieve acidity and reflux thanks to the plant-based Poliprotect complex, making them especially helpful in cases of reflux, acidity, burning or bloating.

When digestion feels heavy or symptoms such as acidity or constipation appear, some people also turn to medicines such as Almax, which works as an antacid to relieve heartburn, or Micralax, a laxative designed for occasional constipation. These are short-term options that may help relieve specific symptoms while the underlying cause is being assessed.

Slow digestion is a common discomfort that is not usually serious, but it can affect quality of life.
