Left Upper Abdominal Numbness After Eating: Causes and Concerns - Gastroenterology and Hepatology

Share to:

Feeling numbness near the left upper abdomen close to the rib cage after eating and lying down?


After eating, I feel a tingling sensation in my upper left abdomen when sitting or lying down, but I don't experience any sensation when I haven't eaten or when I stand or lie down after eating.
The tingling is superficial, likely related to the depth of abdominal muscle engagement, and it is not painful.
I am quite young but weigh around 150 kilograms, so I am quite concerned about potential issues.
I kindly ask the deputy director to address my concerns.
Thank you.

It is likely a posture issue; applying heat and losing weight may help.

More Info


Experiencing numbness or a tingling sensation in the left upper abdomen after eating can be concerning, especially when accompanied by a significant weight factor. While it is good that you are attentive to your body and its signals, it is important to understand the potential causes and when to seek medical advice.

The sensation you describe—numbness or tingling in the left upper abdomen after eating—could be attributed to several factors. One possibility is related to the gastrointestinal system. After eating, especially a large meal, the body directs blood flow to the digestive organs to aid in the digestion process. This can sometimes lead to a feeling of fullness or pressure in the abdomen, which may manifest as numbness or tingling. Additionally, if you are sitting or lying in a position that compresses certain nerves or blood vessels, it could exacerbate this sensation.

Another consideration is the possibility of gastrointestinal issues such as gastritis, acid reflux, or even a hiatal hernia. These conditions can cause discomfort after eating, and in some cases, they may lead to unusual sensations in the abdominal area. Given your weight, it is also important to consider the impact of obesity on your overall health, as it can contribute to various gastrointestinal problems, including increased intra-abdominal pressure.

Moreover, the left upper quadrant of the abdomen houses several important organs, including the stomach, spleen, and parts of the pancreas and colon. Any issues with these organs, such as inflammation or irritation, could potentially lead to discomfort or abnormal sensations after eating. For instance, splenic issues or pancreatitis could present with symptoms that might be mistaken for simple digestive discomfort.

It is also worth noting that anxiety or stress can manifest physically in various ways, including gastrointestinal symptoms. If you find that your symptoms are exacerbated by stress or anxiety, this could be a contributing factor.

Given your concerns about your weight and the symptoms you are experiencing, it would be prudent to consult with a healthcare professional. They may recommend a thorough evaluation, which could include blood tests, imaging studies, or a referral to a gastroenterologist for further assessment. This is particularly important if the numbness persists, worsens, or is accompanied by other symptoms such as pain, changes in bowel habits, or unexplained weight loss.

In the meantime, consider making some lifestyle adjustments that could help alleviate your symptoms. Eating smaller, more frequent meals instead of large ones can reduce the burden on your digestive system. Additionally, maintaining a healthy diet rich in fiber can promote better digestion and reduce gastrointestinal discomfort. Regular physical activity, tailored to your ability, can also help manage weight and improve overall health.

In summary, while the numbness you are experiencing may not be immediately alarming, it is essential to pay attention to your body and seek medical advice to rule out any underlying conditions. Taking proactive steps towards a healthier lifestyle can also contribute positively to your overall well-being.
