Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has brought unpredictable challenges to the whole world by causing Coronavirus disease2019(COVID-19). Although respiratory tract manifestations are the most commonly reported symptoms in COVID-19, early studies reported a low incidence of typical gastrointestinal (GI) symptoms, such as diarrhea, nausea, vomiting, and even liver dysfunctions. However, The prevalence and prognosis of Gastrointestinal system involvement, including gastrointestinal symptoms and liver injury, remains mostly unknown in patients with COVID-19. We aimed to review the effects of COVID-19 on the GI system. Anorexia was the most frequent digestive symptom in adults (39.9%‐50.2%), and diarrhea was the most frequent symptom in both adults and children.Moreover, vomiting was more common in children. Approximately nine percent of adult patients showed vomiting. Almost 36% of children encounter vomiting; nausea is considered for 15% of children. Gastrointestinal bleeding was presented in more than ten percent of children, while abdominal pain was more frequent in severely ill patients.

Cancerous patients, under the chemotherapy or radiotherapy, are at high risk of malnutrition due to the associated complications with the treatment procedures such as chewing problems, dysphagia, nausea etc. Considering the patients’ history of alcohol consumption, smoking or any other diseases and performing several physical examinations are essential in early identification of high-risk patients for nutritional complications, losing unintentional weight and fat free mass. In this review, we tried to briefly explain the risk of malnutrition in patients with head and neck cancers who are undergoing surgery, chemotherapy and radiotherapy. Oral nutrition, nasogastric tube and percutaneous endoscopic gastrostomy are different methods of nutritional interventions, which have been compared due to their efficacy in maintaining the patients’ weight. In this study, we reviewed the results obtained in clinical trials about the efficacy of intense nutritional intervention on limiting the chemoradiotherapy-associated complications in patients with head and neck cancers.
