You can update 1 (or more, just add to the array) column through the DB class.

DB::table('yourTable')->where('id', $id)->update(['remarks' => $request->input('Remarks')]);

You can also do it for a model like so:

bookappoitment::where('id', $id)->update(['remarks' => $request->input('Remarks')]);

It's in the Laravel documentation here.

          <textarea name="remarks" rows="10" placeholder="Remarks">{{$addremarks->Remarks}}</textarea>
