Why you have nasty stomach issues months after suffering covid
A nutritionist has revealed why people are continuing to suffer from nasty stomach issues months after recovering from Covid – and the easy ways to get your digestive health back on track.
Australian nutritionist Lee Holmes said she’s seen many patients visit her clinic with lingering gut issues after having Covid including bloating, reflux and flatulence to constipation, diarrhoea and leaky gut.
One in three people with Covid have suffered from gastrointestinal symptoms. with studies showing those with better gut health had less severe symptoms.
Australian nutritionist Lee Holmes said she’s seen many patients visit her clinic with lingering gut issues after having Covid including bloating, reflux and flatulence to constipation, diarrhoea and leaky gut.
Lee says this is because the gut and respiratory tract share an immune system, known as the gut-lung axis which is detailed further in a number of microbiology studies.
‘This axis is bi-directional, which means if the gut is affected by bacteria, the lungs will be impacted too, and vice versa,’ she explained in a blog post.
‘There are also around 100 times more receptors in the GI tract than respiratory organs, so the gut may be able to house more viruses when it acquires an infection’ she explained.
Lee said that when a person gets Covid cytokines – small proteins that are crucial in controlling the growth and activity of other immune system cells and blood cells – enter the body through the lungs.
Lee says cruciferous vegetable, cauliflower are excellent sources of fibre – which help maintain a healthy gut
This causes all-over body inflammation and once these cytokines reach the gut, the virus can travel through veins that drain blood from the digestive tract, impacting the all-important vagus nerve, which is responsible for the regulation of internal organ functions, such as digestion, heart rate, and respiratory rate.’
‘Once this occurs, the disease impacts the gut barrier, altering bacteria within the gut, increasing its permeability and causing more inflammation,’ she explains.
‘Increased intestinal permeability, which is also known as leaky gut, allows the bacteria to circulate, exacerbating the illness. When this happens, we can experience a range of digestive discomfort symptoms, like bloating or flatulence.
‘To make matters worse, the medications taken for other symptoms of COVID can cause side effects like nausea and diarrhoea.’
Research from the Chinese University of Hong Kong found people suffering with Covid-19 had a ‘significantly altered’ microbiome composition.
Separate research from South Korea found people with a poorly functioning gut are more likely to develop severe Covid-19 because the lack of healthy microbes makes it easier for the virus to infect cells in the digestive tract.
The team from Hong Kong examined blood, stool and patient records from 100 hospital patients with Covid-19 between February and May 2020, and 27 of these patients also provided samples 30 days after the infection had passed.
Researchers also collected samples from 78 people without Covid-19 who were taking part in a microbiome study before the pandemic.
The study concluded the gut microbiome may be involved in the ‘magnitude of Covid-19 severity possibly via modulating host immune responses’.
