Dizziness, fatigue from standing for long periods, back pain, and gastrointestinal discomfort?


Hello Doctor: In May and June of this year, I visited a clinic due to some pain in my upper left abdomen and was treated with a proton pump inhibitor (PPI).
At that time, my stomach condition fluctuated between good and bad.
Subsequently, in early October, I underwent an endoscopy, which diagnosed me with gastritis combined with gastroesophageal reflux disease (GERD).
I have been taking PPIs for nearly five months, and I have now stopped the medication as per the instructions of my gastroenterologist.
Currently, I no longer experience pain in my upper left abdomen, but I still feel slightly nauseous after drinking tea or coffee, and I experience mild cramping and discomfort near my ribs after meals, along with slight discomfort in my back.
Over the past month, I have also experienced some soreness on both sides of my spine (more discomfort on the left side than the right), corresponding to an area extending from just below my heart down to the fourth lumbar vertebra, with the soreness being much more pronounced than the pain.
Additionally, I have recently felt dizzy and weak when standing or walking, and the symptoms became more pronounced when I was standing in direct sunlight, resembling signs of heat exhaustion.
Could you please advise whether the back soreness and dizziness/fatigue symptoms are related to my gastrointestinal discomfort or if they are independent issues? Also, how can I improve these symptoms? Thank you for taking the time to respond.

Hello, internet user: Gastroesophageal reflux rarely presents with symptoms such as spinal pain or dizziness and weakness.
It is recommended that you seek evaluation at a family medicine clinic; if symptoms worsen, it is advisable to go to the emergency department immediately.
Wishing you good health.

The connection between gastrointestinal issues and back pain, as well as symptoms like dizziness and fatigue, can be complex and multifaceted. Your experience with left upper abdominal pain, subsequent diagnosis of gastritis and gastroesophageal reflux disease (GERD), and the ongoing symptoms you describe, including back pain and dizziness, warrant a thorough understanding of how these systems may interact.

Firstly, it is important to recognize that the gastrointestinal (GI) system and the musculoskeletal system are interconnected. Pain from the GI tract can often be referred to areas in the back, particularly in the thoracic and lumbar regions. This is due to the shared nerve pathways that innervate both the abdominal organs and the back. For instance, irritation or inflammation in the stomach or intestines can lead to referred pain in the back, which may explain your experience of discomfort in the area corresponding to your heart and extending down to the lumbar region.

In your case, the gastritis and GERD you have been diagnosed with can lead to symptoms such as bloating, discomfort after eating, and even nausea. These symptoms can create a cycle of discomfort that may lead to muscle tension in the back as you adjust your posture to alleviate abdominal pain. Additionally, the discomfort from bloating can cause you to adopt a protective posture, which may further strain your back muscles.

Regarding your recent symptoms of dizziness and fatigue, these can also be linked to gastrointestinal issues. Chronic GI problems can lead to malabsorption of nutrients, which may result in deficiencies that contribute to feelings of fatigue and weakness. For example, if your body is not absorbing enough iron or vitamin B12 due to ongoing digestive issues, you may experience symptoms of anemia, which can include dizziness and fatigue. Furthermore, dehydration from gastrointestinal disturbances, such as diarrhea or vomiting, can exacerbate these symptoms.

The fact that you have experienced these symptoms in conjunction with standing or walking, especially in hot weather, suggests that your body may be struggling to maintain proper hydration and blood circulation. This can lead to feelings of lightheadedness or faintness, particularly if you are not adequately hydrated or if your blood pressure drops when standing (orthostatic hypotension).

To address these interconnected issues, consider the following recommendations:
1. Dietary Adjustments: Pay attention to your diet and identify any foods that may exacerbate your GERD or gastritis symptoms. Avoiding spicy, acidic, or fatty foods, as well as caffeine and alcohol, can help reduce irritation in the stomach.

2. Hydration: Ensure you are drinking enough fluids throughout the day, especially in hot weather. Dehydration can lead to dizziness and fatigue, so aim for at least 8-10 glasses of water daily, adjusting for activity level and climate.

3. Posture and Movement: Be mindful of your posture, especially when sitting or standing for long periods. Gentle stretching and strengthening exercises for your back can help alleviate discomfort. Consider physical therapy if your symptoms persist.

4. Medical Evaluation: Since your symptoms have been ongoing and are affecting your quality of life, it may be beneficial to follow up with your gastroenterologist or a primary care physician. They may recommend further evaluation, such as blood tests to check for nutrient deficiencies or imaging studies to assess your back pain.

5. Stress Management: Stress can exacerbate both gastrointestinal and musculoskeletal symptoms. Techniques such as mindfulness, yoga, or counseling may help manage stress levels and improve your overall well-being.

In conclusion, while your back pain and dizziness may be related to your gastrointestinal issues, it is essential to approach these symptoms holistically. By addressing your diet, hydration, posture, and stress levels, you may find relief from both your gastrointestinal discomfort and associated back pain. If symptoms persist or worsen, further medical evaluation is warranted to rule out any underlying conditions.
