Generally, the gall bladder is not involved in alcohol metabolism and should not be affected by consumption of alcohol. The gall bladder is simply a temporary storage space for bile that is produced by the liver. Bile is necessary for proper digestion of fats, but the liver does not produce bile on demand. Instead, it produces bile almost constantly, and this bile is stored in the gall bladder until it is needed. In the meanwhile, the gall bladder also concentrates the bile, making it more potent. When we eat foods that contain a lot of fat, a signal is sent to the gall bladder to release the stored bile. The bile is then released into the duodenum through the bile duct.
Alcohol consumption, even if excessive, should not affect the bile duct in any way, but you will need to consult a doctor to be sure. In any case, it is advisable that you consult a doctor about this pain, because it may be a symptom of some serious problem. Conditions that affect the liver could also cause pain in the area of the bile tract, or in the liver itself. Abdominal pain is not easy to diagnose, especially for a lay person, so you should not simply assume that you have a gall bladder problem. Apart from the location of the pain, there are several factors that are taken into consideration when diagnosing abdominal pain. You have only mentioned two factors – the location and the precipitating factor. The nature of the pain, and the duration for which it lasts, also need to be considered.
Gall bladder problems usually cause pain in the upper right part of the abdomen. However, there are other conditions that can also cause pain in the upper part of the abdomen. Since this pain seems to develop after consumption of alcohol, it could originate in the stomach itself. You may be suffering from stomach ulcers or gastritis (inflammation of the stomach lining), which is being aggravated by the alcohol consumption. It is important that you do not neglect this problem. The symptoms may seem very mild right now, and may not show any signs of worsening; however, the problem itself could steadily worsen till it suddenly turns into a medical emergency.
Till the problem is solved, it is advisable that you avoid consuming alcohol, as well as spicy food. You should also avoid fatty foods, just in case it is a gall bladder problem after all.
