Hi, Antibiotics can disrupt the natural balance of bacteria in the digestive system, leading to digestive issues such as constipation. Additionally, antibiotics can also cause side effects such as mouth ulcers, body aches, and restlessness. Constipation can be caused by a variety of factors, including dehydration, lack of fiber in the diet, and changes in the gut microbiome. To alleviate constipation, it is important to ensure that you are drinking plenty of fluids, eating a diet high in fiber, and staying active. Mouth ulcers can also be a common side effect of antibiotics, particularly if they are taken for an extended period. To alleviate the discomfort of mouth ulcers, you can try using a mouthwash or oral gel designed to soothe the mouth and promote healing. If you continue to experience severe symptoms such as body aches and restlessness, it is important to follow up with your healthcare provider for further evaluation and management. They may recommend additional treatments or adjustments to your antibiotic regimen to address your symptoms and ensure that you are on the path to recovery from typhoid. Take care.
