I dont think it is advisable to take any antibiotics or drugs for parasites until you find out what is causing the inflammation. You already have a dysbiosis and treatment could further unbalance your intestinal flora. Seeing a gastroenterologis would be able to assess your condition and explain the report.
The report suggested that you have a slow stool transit time and it would be wise to find a way to speed that up. Small intestine congestion or constipation is more difficult to treat than large intestine constipation. The longer the stool material stays inside your body the more toxins you adsorb and slow transit time makes the risk of cancer greater.
