Marianna said that doctors 'don't know why' she is suffering with the condition.
"I've been dealing with this for over a year now and I'm frustrated because I want to eat.
"I'm hungry a lot of the time and I just can't because I risk food getting stuck or aspirating on it.

UK has passed Omicron peak & end of pandemic now in sight, experts say
"I could hardly walk and I was having a lot of weird neurological conditions.
"That's why I fight so hard to bring awareness to it because a lot of people didn't believe [me]", she posted on TikTok.
While Marianna has suffered severe side effects from the virus, others currently catching the more mild strain, Omicron, have said it feels more like a cold.
However it won't yet be clear to tell if people who caught Omicron have also been plagued with long-Covid.
A string of hugely positive studies show Omicron IS milder than other Covid strains, with the first official UK report revealing the risk of hospitalisation is 50 to 70 per cent lower than with Delta.
Covid booster jabs protect against Omicron and offer the best chance to get through the pandemic, health officials have repeatedly said.
What is dysphasia and what are the symptoms?
Dysphasia simply means a difficulty to swallow.
It's usually a result of conditions such as a stroke, cancer or multiple sclerosis.
these are the symptoms of the illness:
discomfort when swallowing food or drink
choking or coughing when eating
a feeling that food is stuck in your throat
regurgitation of the food, sometimes through the nose
The Sun's Jabs Army campaign is helping get the vital extra vaccines in Brits' arms to ward off the need for any new restrictions.
Marianna also suffers with Postural orthostatic tachycardia syndrome, which is an abnormal increase in heart rate that occurs after sitting up or standing.
She previously told NBC San Diego that her illness comes in waves and that she has good and bad days.
Marianna explained how she struggled to get to the toilet on her own and said that she 'never thought' Covid could bring someone down of her age.
She was hospitalised for six days with shortness of breath and developed two brain lesions.
During this time she said she didn't think she was going to make it out alive.
It's been reported that close to a million Brits could be suffering with long term symptoms of coronavirus, also known as Long Covid.
Long Covid is when people catch the coronavirus and instead of fully recovering, they suffer symptoms for weeks, potentially months, more.
Long Covid was estimated to be adversely affecting the day-to-day activities of 643,000 people – around two-thirds.
Fatigue was the most common symptom (58 per cent), followed by shortness of breath (42 per cent), muscle ache (32 per cent) and difficulty concentrating (31 per cent).
Long Covid was most common in women and people; aged 35 to 69 years, living in poor areas, working in health and social care and with a disability, data from the Office for National Statistics (ONS) showed.
