Detailed Answer:
Thank you for asking
Stomach cramps and nausea with a week history is worth seeing a doctor. Likely possibilities are gastroenteritis, a stomach discomfort like GERD or gastritis, gallbladder pain but less likely.
Give your husband some antispasmodics, some antacids and prefer baking soda in diet. Eat plenty of fibers and keep the diet soft and get assessed.
If the symptoms resolved with these conservative measures , well and good. Otherwise work up will done to sort out the causes including functional bowel issues like IBS etc.
There is no harm in getting evaluated, and till then do as directed with the conservative measures.
Take care
