Digestive Problems and COVID-19: Symptoms to Look Out For
Published | 6 min read
There are various ways to ease gastrointestinal symptoms if you have COVID-19, be it with modern or traditional methods. Explore your options here.
Getting a fever, dry cough, flu and even shortness of breath are common symptoms of COVID-19, or any viral infection. However, you might also experience digestive problems like diarrhoea, nausea, and vomiting, if your infection is severe.
A study showed that around one in five people who tested positive for COVID-19 had at least one gastrointestinal symptom including constant stomach pain. Out of those who were hospitalised, 25.9% had gastrointestinal issues.
Fortunately, there are multiple ways you can do to ease these symptoms of digestive problems, be it with modern medicine or Traditional Chinese Medicine (TCM). Read on to explore your options.
How COVID-19 Affects Your Gastrointestinal System
Any virus that infects your body will destroy healthy cells and multiply. COVID-19 mainly targets the cells that line your airways, making it hard for you to breathe, and which can lead to pneumonia. Additionally, this infection can also harm your digestive tract and liver tissues.
Look out for the first signs of gastrointestinal symptoms if you test positive for COVID-19. A lack of appetite is the most common symptom, followed by a loss of taste and smell. Up to 34% of patients experience diarrhoea which lasts for about three to five days.
If you’re experiencing any digestive problems, you are more likely to have a positive stool test for COVID-19. It might also take you a little longer to recover compared to those without gastrointestinal symptoms.
Gastrointestinal Symptoms Related to COVID-19
Diarrhoea is the most common symptom in this case, followed by poor appetite, bloating, indigestion, abdominal or epigastric distention, and ironically, even constipation, which is a rare symptom.
According to a study published by the American Journal of Gastroenterology, out of a total of 117 people with gastric distress, about 19.4% saw diarrhoea as their earliest symptom.
If you are unlucky, you might also develop gastrointestinal symptoms with respiratory symptoms, worsening your illness further.
Vomiting is one of the common digestive problems in people with severe symptoms of COVID-19. According to a study, about 3.6% to 15.9% of adults experienced vomiting. However, a high number of 66.7% of children experience vomiting. Researchers analysed that the coronavirus affects a child’s gastrointestinal system more than an adults.
3. Loss of appetite
Lacking an appetite is common among COVID-19 patients. There are many patients who reported that they lost their appetite completely, along with their taste and smell.
One way to combat this is to stay hydrated and eat when you can as your body requires the energy from food to fight the virus. This is because a lack of food and water may cause nausea and abdominal pain.
In one study, about 13.7% of patients experienced gastrointestinal bleeding as a severe symptom. If this happens, hospitalisation is necessary. Consult your doctor right away if you experience constant stomach or abdominal pains.
Ease Digestive Problems with TCM
Physicians who practice TCM can help with symptoms of digestive problems through herbal medication, acupuncture, moxibustion, cupping and even tuina. “These treatments are all formulated carefully by TCM physicians to address the unique body constitution of each individual patient. It’s best to always consult a TCM physician first for a proper assessment,” advised Senior Physician Brandon Yew.
Here are some TCM herbal formulations that your physician might recommend:
Xiang sha liu jun zi (香砂六君子)
Shen ling bai zhu san (参苓白术散)
Bu zhong yi qi tang (补中益气汤)
Xiao yao san (逍遥散)
Chai hu shu gan san (柴胡疏肝散)
Jian pi wan (健脾丸)
Bao he wan (保和丸)
Ban xia xie xin tang (半夏泻心汤)

Xiang lian wan (香连丸)
Wu mei wan (乌梅丸)
Zhi shi xiao pi wan (枳实消痞丸)
