Overfeeding is the number-one cause of high nitrate levels in aquariums. Overfed fish produce much more waste than normal, and when more food is given than they can take in, the uneaten food rots and produces even more wastes. Keeping too many fish in a tank also leads to problems with accumulated wastes.
Symptoms Caused By Esophageal Ulcer. One classic symptom is a dull or burning pain. It is common with all forms of peptic ulcers. The affected person may feel the pain radiating within the areas starting from the navel up to the breastbone.
GERD is also known as gastroesphageal reflux disorder, symptoms of which are heartburn, nausea and vomiting. GERD symptoms are triggered by fatty, spicy or acidic foods, of which lemon juice is one. Lemon juice can exacerbate GERD symptoms as the acid content can irritate the esophageal lining. If you have ulcers, the increased acid content can also irritate the stomach lining and stop the ulcer from healing properly.
