Gastrointestinal issues


I am taking psychiatric medication and I want to ask about my symptoms.
I often experience nausea and vomiting, and I have a poor appetite, only eating two or three bites of rice per meal, which has caused me to lose four kilograms.
However, my psychiatrist says that my symptoms are due to not eating enough.
I also vomit the medication.
My height is 167 cm and my weight is 56 kg; is that still acceptable, or can I not afford to lose more weight?

Hello, based on this calculation, the BMI is approximately 20, which should not be considered underweight.
As for the ongoing vomiting issue, it may be worthwhile to consult a gastroenterologist to evaluate whether there are any gastrointestinal problems.

Gastrointestinal issues related to psychiatric medications are a common concern for many patients. The symptoms you are experiencing, such as nausea, vomiting, and a reduced appetite, can indeed be side effects of certain psychiatric medications. It's important to understand that psychiatric medications, particularly those used to treat conditions like depression, anxiety, and bipolar disorder, can have various effects on the gastrointestinal (GI) system.

Firstly, medications such as selective serotonin reuptake inhibitors (SSRIs), serotonin-norepinephrine reuptake inhibitors (SNRIs), and other psychotropic drugs can influence the gut-brain axis. This is a complex communication network linking the gastrointestinal tract and the brain, which means that changes in one can significantly affect the other. For instance, SSRIs can increase serotonin levels in the gut, which may lead to gastrointestinal side effects like nausea and changes in appetite.

In your case, the loss of appetite and subsequent weight loss (four kilograms) is concerning, especially since you mentioned that you are only able to eat a few bites of food at a time. Your height and weight suggest that you are within a healthy weight range, but losing weight can lead to nutritional deficiencies and other health issues if it continues. It’s crucial to address this with your healthcare provider.

Your psychiatrist's assertion that your reduced food intake is causing your symptoms may hold some truth, but it is also essential to consider that the medications themselves could be contributing to your gastrointestinal distress. If you are experiencing persistent nausea and vomiting, it may be necessary to reassess your medication regimen. Sometimes, adjusting the dosage, switching to a different medication, or adding an anti-nausea medication can help alleviate these side effects.

Additionally, it is important to maintain adequate nutrition during this time. If solid foods are difficult to tolerate, consider trying liquid nutritional supplements or softer foods that may be easier on your stomach. Foods that are bland and low in fat may help reduce nausea. Staying hydrated is also crucial, as vomiting can lead to dehydration.

If your symptoms persist, it may be beneficial to consult with a gastroenterologist. They can help rule out any underlying gastrointestinal conditions that may be exacerbating your symptoms. Conditions such as gastritis, peptic ulcers, or even functional gastrointestinal disorders like irritable bowel syndrome (IBS) could be contributing factors.

Lastly, consider discussing your symptoms with both your psychiatrist and a nutritionist. A nutritionist can help you develop a meal plan that meets your dietary needs while accommodating your current symptoms. They can also provide strategies to help manage your appetite and ensure you are getting the necessary nutrients.

In summary, while psychiatric medications can contribute to gastrointestinal issues, it is essential to take a comprehensive approach to your health. Addressing both the psychiatric and physical aspects of your symptoms will be key to improving your overall well-being. Don't hesitate to advocate for yourself and seek further evaluation if your symptoms do not improve. Your health is paramount, and finding the right balance in your treatment plan is crucial.
