Weak Digestion: Symptoms, Causes And Home Remedies

| Reviewed By Karthika Thirugnanam

A healthy digestive system is a result of a healthy diet and lifestyle. The human digestive system is a complex series of organs and glands meant for processing food. In order to produce energy from the food we eat, the body has to break down the food into smaller molecules that can be absorbed and used for various bodily functions. It is also essential to excrete waste from our body.

Digestion problems are fairly common, especially among those who consume excessive amounts of fried and cheesy foods or heavy meals. Around 1 in 4 people in India are affected by digestion problems [1][2].

Digestive problems or weak digestion can occur when the food is not digested properly or due to underlying problems like gastroesophageal reflux disease, ulcers or gallbladder disease, bile duct issues or food intolerances, which can in turn cause symptoms like bloating, gas, nausea, vomiting, feeling full after a meal, or burning pain in the chest and stomach [3][4].

Today, we will look at what weak digestion is and how you can improve your digestion.


What Does It Mean To Have Weak Digestion?

I think it is safe to suggest that almost all of us have had occasional digestion issues such as an upset stomach, feeling gassy or bloated, heartburn, nausea, constipation or diarrhoea. As the name suggests, weak digestion is when your digestion process does not function the same way as that of a healthy human being and causes irritability and discomfort [5].

If you have a weak digestion, where your digestive system fails to function normally, you may experience heartburn to some unexpected (and embarrassing) gas passing and more. Poor digestion silently leads to several ill-health conditions like migraines, anxiety, depression, eczema, acne, joint pain and allergies [6]. Hence foods that impair your digestive system should either be consumed in limited quantities or completely avoided.


How does the digestive system work?

Before getting into the topic of weak digestion, you need to understand how your digestive system works. Digestion is a long process that involves not only your stomach but also many organs that form the digestive tract [7][8].

  • Digestion begins in the mouth, where saliva breaks down the food while you chew.
  • When the food is then swallowed, the chewed food moves to the oesophagus, which connects your throat to the stomach.
  • The food is then pushed down by the muscles in the oesophagus to a valve at the bottom of your oesophagus.
  • Upon reaching the stomach, the stomach acids break the food down and move it to the small intestine.
  • In the small intestine, digestive juices from several organs, like the pancreas and gallbladder further break the food and the nutrients are absorbed.
  • The remaining goes to the large intestine, where all the water is absorbed.
  • What is now left is the waste, which moves out of your body through the rectum and anus.
  • This is how a healthy digestion process normally takes place. In the case of a person with weak digestion, problems can occur anywhere along the way [9].


What Are The Causes Of Weak Digestion?

Here is a list of some of the most common causes of weak digestion.

An unhealthy diet: A diet consisting of processed food, junk food or a one that comprises a high amount of carbohydrates, refined sugar, salt and fats can lead to an unhealthy digestive system [10]. Foods that are low in essential nutrients can slow the digestion process and cause bloating and irritable bowel syndrome [11].

Lack of physical activity: A sedentary lifestyle can cause the development of more than forty medically recognised and chronic diseases such as coronary heart disease, type 2 diabetes, obesity, mental illness, dementia and different types of cancer [12]. A lack of regular physical activities can weaken your digestive system [13], as studies have consistently shown that a regular exercise regimen can help treat constipation and promote healthy digestion [14].

Lack of fruits and vegetables in diet: It is no news that fruits and vegetables are essential for maintaining a healthy diet. Consuming fewer or no vegetables and fruits can lead to constipation and other digestive ailments [15]. The fibre found in fruits and vegetables plays an important role in maintaining healthy gut bacteria as well.

Lack of sleep: Sleep deprivation is a major reason for increased appetite, which can directly increase the risk of weak digestion [16]. Apart from craving for unhealthy snacks while having the sleepless night, untimely these poor eating habits cause fluctuations in hormone levels as well. Not getting ample sleep can also lead to digestion-related issues such as gastroesophageal reflux disease, irritable bowel syndrome and functional dyspepsia [17][18].

Insufficient water intake: Studies point out that dehydration is one of the leading causes of an unhealthy digestive system, which can lead to constipation, gastritis and acid reflux because the stomach does not have enough water to produce digestive acid required for digesting your food [19]. Most healthy adults need to drink at least 7 to 8 glasses of water daily and may require more if they live during hot weather or if one engages in strenuous activities.

Overeating: One of the major causes for weak digestion, overeating slows down the digestive process causing the food you ate to remain in the stomach for a longer period of time and be more likely to turn into fat [20]. Insufficient digestion may result in various problems like heartburn and acid reflux, vomiting and nausea [21].


What Are The Symptoms Of Weak Digestion?

Apart from your lazy habits, the modern lifestyle makes it easy for one to develop weak digestion from high-stress levels, too little sleep, take-aways etc. These are the signs and symptoms which may indicate that you have weak digestion [22][23]:
